Weber Genesis S-435 Gas Grill vs Weber Genesis II S-435 Propane Grill

Both are 4-burner stainless Genesis grills with a side burner, a sear zone and about 994 square inches of total cooking area. The S-435 (previous model) is the newer design: it adds the WEBER CRAFTED frame for drop-in grillware and the larger sear zone, so it is the better pick for anyone who wants to expand the grill later. The Genesis II S-435 is the older generation and is the better buy only if it costs clearly less. Check the current price at each store before deciding.

What reviewers say

Weber Genesis S-435 Gas Grill

  • 4.6 / 53,046 ratings

Rated 4.6 out of 5 from 3,046 ratings, the S-435 is well regarded for even heat, the sear zone and room to cook for a crowd. Owners mainly note its size and weight and the extra cost of the tank and grillware.

What people mention
  • Sear zonePraisedOwners say the sear zone reaches high heat and sears several steaks at once.
  • Cooking spacePraisedThe primary and second-level grates together handle meals for a crowd.
  • BuildPraisedReviewers describe the stainless body and lid as solid and well finished.
  • FootprintCriticisedIts 68.5-inch width with the lid open takes up significant patio space.

Weber Genesis II S-435 Propane Grill

Owners of the Genesis II line generally praise even heating, the hot sear zone and sturdy build. Common complaints center on assembly time, the open cart and the price of replacement parts.

What people mention
  • Sear zonePraisedOwners say the sear zone reaches high heat fast and gives steaks a good crust.
  • Heat evennessPraisedCooks report consistent temperatures across the main grates with few hot spots.
  • Build qualityPraisedOwners describe the firebox and frame as sturdy and likely to last many seasons.
  • AssemblyCriticisedBuyers say putting it together takes a couple of hours and two people.

Questions and answers

Which is better for searing steaks?
The Genesis S-435. Its sear zone is rated 12,000 BTU and is Weber's largest, so it fits more steaks at once than the Genesis II S-435.
Can I use WEBER CRAFTED grillware on the Genesis II S-435?
No. The drop-in grillware needs the WEBER CRAFTED frame, which only the newer S-435 has.
Is the S-435 worth the extra money?
Yes if you plan to add grillware or sear for a crowd. If you just want four burners and a side burner, the Genesis II does the same job for less.
Do either come with a propane tank?
No. The S-435 lists a 20 lb tank as sold separately, and the Genesis II is also a propane grill without a tank included.
Which lasts longer?
Both use stainless steel burners and a stainless finish, so life depends on care and cover. The S-435 is newer, so its parts will stay available longer.
How much counter space do they need?
Both are 48 in high and 27 in deep with the lid closed. The S-435 needs 63 in of height and 68.5 in of width with the lid open.
