We pick the Weber Spirit E-425 Gas Grill
Buy the E-425 and keep the $20, unless the grill has to move. Every figure above the cart is the same on both: 35,000 BTU across four stainless burners, 428 sq in of primary grate, 82 BTU per square inch, 103 pounds. What the letter buys is four swivel casters in place of two wheels and two fixed feet, plus an inch less depth with the lid down.
What actually differs
-
The cart, and nothing above it
Weber publishes the same burner output, the same primary and total grate, the same weight and the same cast-aluminium cookbox for both. The E-425C changes how it rolls and nothing about how it cooks.
-
Four swivel corners against two wheels
The E-425 pivots on two wheels and drags two fixed feet; the C steers in any direction and locks two of its four casters. On a tight patio or in and out of a garage that is a real difference, and on a slab it never leaves it is none.
-
The part you paid extra for has the shortest warranty
Ten years reaches the cookbox and the burner tubes on both grills. The casters sit in the two-year tier along with the paint, so the upgrade is the component least covered.
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 →
Same two Boost Burners the E-325 gets, now asked to serve 68 more square inches of primary grate.
Boost is a position past high on two of four knobs, not extra hardware and not extra published input.
Four burner tubes carry ten years here, but paint and everything unlisted still fall off cover at two.
Ten years reaches the cookbox and the burner tubes, while the casters you paid extra for sit in the two-year bucket.
Cast iron, stainless bars and a closed cabinet, holding 103 pounds steady across a 51.80 inch frame.
A cast-aluminium cookbox and 103 pounds ride on four castering corners, inside a footprint shallower than the E-425 cart.
Four Snap-Jet knobs light one at a time, so the red pair sets a sear side in seconds.
Four swivel casters steer in any direction, where the $629.00 E-425 pivots on two wheels and drags two fixed legs.
Stepping from $499.00 to $629.00 adds a burner and grate, but not a third Boost Burner.
Twenty dollars buys a cart and nothing above it, and Weber never explains the letter you are paying for.
The grease tray slides clear in one motion, yet 428 square inches of enamel all have to stay unchipped.
The grease tray pulls clear in one motion, but 428 square inches of enamel and four casters both collect fallout.
Heat density
Burner output over the surface it has to heat, derived in each review from that cooker's own published figures. A bigger number is not a better grill — it says how hard the cooker can drive its grate, nothing more. All grills ranked →
Published figures that differ
Quoted from each maker's own specifications, as each review records them. Figures the two products publish identically are left out — only the differences are listed.
Which one is for you
You move the grill often — a narrow patio, winter storage, or a surface you have to steer across.

Every score and figure on this page comes from our own reviews of these two products, linked above. We have not tested them side by side in one place; the comparison is between two full reviews, each built from the maker's published specifications and documentation. Prices move, and the ones quoted are the ones each review checked on its own date.
