We pick the Weber Genesis E-315 Gas Grill
Spend the extra $170 on the Genesis E-315, unless pans are how you cook outdoors. It gives 513 sq in of grate against 428, two clear side tables and twelve years on the cookbox. The E-435 answers with a Sear Zone, 82 BTU per square inch against 76, and a 12,000 BTU burner set into its left table. Our reviews score the Genesis higher, and nearly all of that gap is reliability.
What actually differs
-
Two ways to free up grate
The E-435 makes room by moving pans off the grill onto its side burner. The E-315 simply starts with 85 more square inches. One cooks elsewhere; the other is bigger.
-
Two prep tables against one
Both Genesis side tables are fixed and free for platters and prep. On the E-435 the left one is a burner well under a hinged cover, so a pan there leaves one surface for everything else.
-
The Spirit wins the heat score and loses the long one
Our Spirit review scores heat higher, for the Sear Zone and the extra burner. Our Genesis review scores long-term reliability 2.5 points higher, because the side burner sits in Weber's two-year tier.

Counts for 25% of the scoreWeber Genesis E-315 8.0Spirit E-435 8.5 Better by 0.5Why the Spirit E-435 scores 8.5Four burners and 35,000 BTU unchanged from the E-425, with 12,000 more sent where no grate sits.
Why the Weber Genesis E-315 scores 8.0
Even heat is the whole claim, but 39,000 BTU over 513 square inches is not a dense fire.

Long-term Reliability
Counts for 20% of the scoreWeber Genesis E-315 9.5 Better by 2.5Spirit E-435 7.0Why the Weber Genesis E-315 scores 9.5Twelve years on cookbox and lid, ten on everything sitting in the fire, five under the rest, better cover than rivals at this price.
Why the Spirit E-435 scores 7.0
The side burner appears in none of Weber's longer warranty tiers, so the paid-for part carries two years.
