Our verdict

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

  1. 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.

  2. 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.

  3. 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.

    Weber Genesis E-315 8.0
    Spirit E-325 9.0 Better by 1.0
    Why the Spirit E-325 scores 9.0

    Two Boost Burners give one grate two real working heats, at close to 86 BTU per square inch over the primary grate.

    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.
