Weber Genesis E-315 vs Spirit E-325
513 sq in at 76 BTU per sq in against 360 sq in at 86, with a Sear Zone. The Spirit E-325 costs $350 less than the Genesis E-315. What the Genesis buys.
We pick the Weber Spirit E-325 Gas Grill
Buy the Spirit E-325 unless you regularly fill more than 360 sq in. It runs 31,000 BTU through 360 sq in, about 86 BTU per square inch, with two Boost Burners feeding a Sear Zone, for around $549.00. The Genesis E-315 spreads 39,000 BTU over 513 sq in, about 76 BTU per square inch, with no sear area at all, for $899.00. The extra $350 buys grate and warranty years, not heat.
What actually differs
-
The cheaper grill burns denser and has the sear side
86 BTU per square inch against 76. The Spirit also color-codes a Sear Zone onto its panel. The E-315 boosts no burner and marks no sear area, so a hot side means turning a knob down elsewhere.
-
The Genesis money goes into the middle of the warranty
Both give the cookbox a long headline and the paint two years. The gap is underneath: the E-315 covers grates and Flavorizer bars for ten years and remaining parts for five. The Spirit gives those five and two.

Totals 0.12 apart, reached from opposite ends
Our reviews score them 8.45 and 8.57. The Spirit wins on heat, ease of use and value; the Genesis wins on long-term reliability. The gap is small enough that the buyer's table size still decides.
The scorecard, side by side
Both reviews are scored on the same six weighted categories, each bar on the same 0–10 scale, and every cell carries the reason that review gave. A row is marked won only where the two differ by a tenth or more. How we score →
Even heat is the whole claim, but 39,000 BTU over 513 square inches is not a dense fire.
Two Boost Burners give one grate two real working heats, at close to 86 BTU per square inch over the primary grate.
Twelve years on cookbox and lid, ten on everything sitting in the fire, five under the rest, better cover than rivals at this price.
Ten years on the cookbox, lid and burner tubes, but only two on everything remaining, paint included.
Porcelain-enameled lid and cast iron grates, stainless Flavorizer bars, painted steel doors, 162 pounds of cart.
Porcelain-enameled cast iron, stainless Flavorizer bars and a closed cabinet, at 98 pounds on two wheels.
Electronic ignition, six tool hooks and two fixed side tables, against an assembly job and 162 pounds.
Snap-Jet lights each burner one-handed, which is exactly how a two-heat cook gets set up.

Around $549.00 buys the same Sear Zone and cast iron as the EX-325 for $50 less, though Weber Works accessories cost extra.
The grease tray pulls straight out, but chipped enamel corrodes and paint carries only two years.
