If you’re looking to invest in a new gas grill, chances are you’re trying to decide between the Weber Spirit or Weber Genesis lines.

In this guide, we’ll take you through both the Spirit and Genesis Weber grill lines, including the latest updates from 2019.

Although both lines use excellent components and smart grill design, both are also subtly different and can better serve different owners.

In our opinion the best value gas grill has to be the Weber Spirit II E-310.

If you can stretch your budget, then the the Genesis II E-435 hits the sweet spot between price, size and functionality. The inclusion of a dedicated sear burner makes this the obvious choice for steak fanatics.

Read on for more in-depth comparisons between these two lines of grill.

Weber Spirit vs. Genesis – What’s the Big Difference?

The Spirit II and Genesis II are the two most popular gas grill lines that Weber sell.

The Spirit II line is designed for people who prioritize value for money over extra features.

While the Genesis II is made for the lifestyle griller who has cookouts often and is willing to pay more for higher quality and extra functionality.

The Geneis II lineup was re-released in 2019 with a number of improvements, while the newest Spirit II line came out in 2018.

You may also see some of the older Spirit and Genesis grills around (without the II in the name). I would avoid these unless you get a really good deal as they are now out of date.

Key differences between Spirit and Genesis grills:

  • Spirit grills are simpler and are generally cheaper
  • Some models of Genesis II include a sear station and enclosed cart
  • Genesis range includes more burners, and higher BTU numbers

Despite these differences, both grills are made by Weber, so there are a few great features and upgrades that they share:

Similarities between Spirit and Genesis:

  • Both are iGrill 3 compatible (more on this later)
  • Both have the new and improved GS4 grilling system
  • Both share the same warranty.

Both grills come with a 10-year 100% Weber guarantee. This guarantee covers all of the parts of whichever grill you end up going with if they suffer from irregular damage or malfunction.

Note that this does not cover normal wear and tear which might be obtained over a regular 10 years of use.

iGrill compatible

Another feature that is standard in both the modern Spirit and Genesis lines is iGrill 3 integration.

iGrill is Weber‘s own brand of Bluetooth meat thermometer.

This is a mounted thermometer that can be placed at the side of your grill. This can be connected to your smartphone via an app, letting you monitor the internal temperature of up to four different meat pieces.

The app will alert you when grilling is done and it’s time to eat. This lets you step away from your grill and mingle with your guests or tend to other food that needs your attention.

Weber Spirit Overview

It’s a little bit unfair to call the Spirit II a “starter grill”, but when you compare it to the Genesis II that’s definitely what Weber are going for.

The main two Spirit grills we’ll be looking at are the two burner Spirit II E-210 and the three burner E-310 models.

Both models come in a range of colors and let you choose between liquid propane or natural gas.

These are capable and affordable grills that provide good value for money. The main difference between these two are their areas of cooking space and the latter model’s ability to reverse some of its grates.

Weber Spirit II E-210

This grill is a bit smaller than several of the Genesis grills, but it still has plenty room. You get 450 square inches of cooking space when you account for the warming rack and the main cooking surface.

Both of these areas are warmed by two burners that can emit 26,500 BTUs of heat combined.

The E-210 uses the GS4 grilling upgrades like with the rest of the Spirit and Genesis models.

Another great feature included is the addition of six integrated hooks that let you easily store any of your grilling tools as you switch between them.

There’s an open-cart design on display that gives you even more storage space, and two side tables are attached to the main model.

You can fold the left one down if you’re pressed for space.

Despite its size, you can still implement the iGrill3 thermometer and mount it right on the side for easy internal temperature monitoring.

The grill is equipped with two tires to allow for easy transportation, and they are constructed to be used in all weather types.

What we like:

  • Left table can be folded down
  • Good storage space
  • Excellent warming potential between burners

Weber Spirit II E-310

The E-310 uses three stainless steel burners instead of two.

The combined heat output from these burners can equal 30,000 BTUs. When you consider the 529 square inches of cooking space between the main area and the warming rack, this is enough heat and space to serve a larger family between 5 and 7 people.

The cooking grates are made of porcelain-enameled cast-iron.

These transfer heat very well and maintain sturdiness and rigidity even after many different cookout sessions.

In addition, some of these grates are reversible between the thin side or a wide side. You can use the thin side for fish or other delicate meats and the wider side for steaks and similar cuts.

There’s also an easy-to-read fuel gauge that you can use to never be caught off guard when it’s time to refuel. The fuel tank is mounted outside the grill, too, so replacing it only takes a few seconds and lets you get back to the cooking quickly.

The grill uses an open cart design with plenty of storage space beneath the main unit. The same two all-weather wheels are present to allow for easy movement and storage, and this Spirit grill also has six integrated hooks for easy organization.

As before, there are two sides tables to give you more space to cut and season your meat. The left one is capable of being folded down.


  • Good grate construction
  • Reversible grates
  • Plenty of cooking space
  • Left table can be folded down

Weber Genesis Overview

The Genesis II lineup gives you more models to choose from. Unlike the Spirit II there are no two burner models.

You start with the basic three burner E-310 and go up from there.

Again, the primary differences between these models are their variable areas of cooking space and some extra attachments or secondary burners on the later grills.

Weber Genesis II E-310

The E-310 is the most basic model in the Genesis lineup.

It still provides you with 513 square inches of cooking area.

The warming rack can be tucked away and extended depending on your cooking needs, which is a bit of versatility we really like.

The cooking grates are also porcelain-enameled and cast-iron for good heat diffusion and durability.

These grates are also reversible to a thinner side and thicker side as we mentioned with the previous Spirit grill.

Three burners beneath the cooking area combined for 37,500 BTUs of heat. The power goes into 3 large-sized burners.

The fuel tank is located on the right-hand side and is covered up, but you can monitor your fuel level via a convenient gauge on the front of the grill.

As with the Spirit models, this grill uses the GS4 Grilling System and you can mount the iGrill 3 thermometer if you desire.

This grill also uses an open cart design so you can store your equipment beneath the main unit. Six hooks are integrated for your various grilling tools, and you can make use of two worktables on either side for more working space.

Unlike the Spirit models, the left-hand table does not fold down.

Two all-terrain wheels are present to allow for easy transportation. These are bolstered by locking casters that you can engage to make sure that your grill doesn’t roll away with your tasty grilled meal!


  • Good grilling space
  • Good grate construction
  • Reversible grates
  • Convenient fuel gauge
  • Lockable casters

Weber Genesis II E-435

Packed with extra features including a closed cart, side burner and sear station, the E-435 is definitely our favorite model in the Genesis lineup.

As well as the extra features, the E-435 is larger than the E-310 and includes four burners instead of three.

You can also get the extra features with a smaller three burner design with the E-335.

The burners on the E-435 combine to heat 646 square inches of cooking space with 48,000 BTUs of heat not counting the 9,000 BTUs coming from the sear station burner.

With the sear station going you can hit temperatures up to 800°F for restaurant quality steaks.

There is a warming rack that you can tuck away or bring back at your discretion.

The grates are also reversible, porcelain-enameled and cast-iron, so you get the same quality cooking surface as the other models, just more.

The open cart has been replaced with a closed cart design that gives you better storage options for grill accessories.

It can, of course, make use of the GS4 Grilling System and iGrill 3 thermometer.

What we like:

  • Addition of sear station makes this a very versatile grill
  • Reversible grates of good construction
  • Four burners main burners offer plenty of cooking space
  • Improved storage

Weber Genesis II LX E-640

This is a much larger grill than the others we’ve looked at so far.

The LX E-640 is packing a ludicrous six stainless steel burners that combine for 72,000 BTUs of heat. This heat is dispersed over 770 square inches of cooking space.

This is enough high-heat cooking area need more than 12 people at one time.

The grates here are different from the other Spirit and Genesis models. These are made from premium stainless steel rods, which help to defuse the heat even more effectively and retain heat for longer.

If you’ve ever wanted beautiful sear marks on your grilled meat, you can accomplish those with this grill.

There’s a Tuck-Away warming rack that you can extend or store at your discretion and a side burner that you can make use of to warm sauce or another tasty addition to your meal.

Even more impressive is the High+ setting that you can initiate at any point during the cooking process. This is accomplished via a simple button and it boosts heat anywhere on the cooking surface you desire. It only takes about a minute to preheat and lets you raise the grill’s internal temperature higher than many other comparable models.

Two stainless steel side tables are present once again with integrated tool hooks to let you store all of your implements. Its storage space is protected via cabinet doors, as well.

An LED light has been installed inside the grill to let you see the true color of each piece of meat, even in dubious outdoor lighting conditions. If you are cooking at night, you can use the light-up controls on the grill’s front to keep the cookout going even after the sun has gone down.

What we like:

  • Excellent grate design
  • LED lights for nighttime cooking
  • Stainless steel side tables
  • High+ setting
  • Six stainless steel grates
  • Tuckable warming rack

Alternative Option – Weber Summit

The Summit Weber‘s high end grill line, aimed at people who want even more quality and versatility.

The Summit utilizes 4 or 6 48,800 BTU main burners depending on the variance you purchase, along with 2 additional burners:

  • 10,600 BTU burner for sear cooking
  • 10,600 BTU rotisserie burner.

This gives you even more versatility than ever before.

It also utilizes an LED tank scale display and fuel gauge to let you easily read both measurements during day or nighttime cooking.

The rotisserie system can be tucked away at any time. A flip-up motor and separate spit and fork storage compartment have also been integrated into the model.

Overall, this is an even higher-power choice if you need a grill that can handle more meat for more people or you want the ability to cook more types of meat at the same time.

All of this functionality comes with a much higher price tag, however.

The GS4 High Performance Grilling System

All Genesis grill have come equipped with the GS4 Grilling System since 2017, while the Spirit II has had them since 2018.

Weber uses a lot of marketing jargon, but essentially the upgrade has four major components:

  • Infinity Ignition – this ignition system includes heavy-duty wire coatings to prevent heat from damaging the ignition process. This system also has batteries that are easier to replace than those on similarly-priced grills and an ignition module that is totally protected. The electrodes have also been improved to make them more reliable. All of these implements combine so that igniting your grill is consistent and dependable for the duration of the grill’s lifespan.
  • Flavorizer Bars – these are triangular bars implemented beneath the cooking surface of each grill line. They act as deflectors for grease that drips from the meat you’re grilling, preventing the grease from reaching the burner. This prevents any flareups from messing with your cooking. At the same time, by catching the grease that drips from the meat, these bars also cause it to smoke and sizzle, “flavorizing” your food.
  • Upgraded Burner Tubes – previous Weber grill models occasionally had issues with uneven heating on the grilling surface. The Spirit and Genesis lines avoided this issue thanks to the upgraded burner tubes, as they are tapered and reversible. Both of these aspects allow the heat to be dispersed evenly across the cooking surface.
  • Grease Management – If any grease doesn’t turn to smoke due to the flavorizer bars, these droplets will roll into a collection pan that is much easier to clean after grilling is done.

Wrapping it up

So, which grill line is for you: the Spirit or the Genesis?

That greatly depends on your overall budget and how many people you are planning to feed during your next cookout.

The Spirit line is more affordable and its models are generally smaller, making them easier to store. The Genesis line has grills that are usually larger, allowing you to cook for more people, for slightly higher prices.

Either way, both lines make use of some great Weber innovations, like the GS4 Grilling System and the iGrill 3 thermometer.

I hope this guide helped you answer your questions about the Spirit and Genesis, and you’re now ready to decide.
