It depends — and here is on what
This turns on how many you feed and how much floor you have. For two people on a balcony, the 18 does the job for $129.00. For a family, its 240 sq in splits thin once the coals are banked, and the Performer's rails hold a real cool side on 363 sq in. If the table is not the draw, both reviews point to the $149.00 Original Kettle 22 in between.
What actually differs
-
$320 buys 123 sq in and a cart
The Performer's grate is 363 sq in against 240. The rest of the gap is a painted steel table, a wide shelf and a frame, none of which cooks anything.
-
Two zones on 240 sq in is cramped
Bank the coals in the 18 and each half holds a couple of steaks. On the Performer, Char-Rails pin the bank in place on a bigger grate, so indirect chicken has room.
-
A dial and flip-up sections, or feel
The 18 lists no thermometer, so its dampers are set by feel. The Performer adds a lid dial, and its hinged grate lets coals go in without moving the food.
-
Beside a door, or across a patio
The 18 is 36 in tall and tucks under a balcony rail. The Performer's cart runs 40.25 in side to side, which on a small balcony becomes an obstacle.
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 →
Lid and bowl dampers give the usual kettle control, but a 240 sq in grate leaves a cramped cool side once coals are banked.
The Original Kettle 22's bowl and 363 sq in, plus Char-Rails and a hinged grate that hold two zones and feed a long fire.
Enamelled bowl and lid carry ten years, the aluminium legs shrug off rust, and only the grate and small parts sit on two.
Bowl and lid carry 10 years like every 22 in kettle, but the painted-steel cart, table and wheels sit in a 2-year bucket.
Porcelain enamel and glass-reinforced nylon handles are the real thing; the plated grate and wire leg brace are where the money was saved.
Hand-applied porcelain enamel on bowl and lid is excellent; the grate is plated steel and the side table is painted steel.
No thermometer is listed, so dampers are set by feel, and a 5 in lid height turns away tall roasts.
Beats the Master-Touch's kit of hinged grate, Char-Rails, Tuck-Away holder and lid dial by adding a side table and a shelf.
At $129.00 against $149.00 for 363 sq in, the bigger Weber kettle buys far more grate for each extra dollar.
$449.00 buys the $149.00 Original Kettle 22 cooking hardware plus $300 of cart, which is steep for a table and a shelf.
One-Touch sweeps ash into a shallow open catcher in a few strokes, and the enamel wipes down; nothing encloses the ash.
The One-Touch sweep drops ash into an enclosed, wind-proof catcher, and Weber warrants that system separately for 5 years.

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.
