No single winner. Here is how to choose.
It depends on how many pizzas you bake in a row. Both take a 16 inch pie and reach 950 F. The Koda 16 costs around $498 and weighs 40.1 lb, but Ooni itself measured a 360 F swing across its stone, so you turn every pie and watch the hot side. The Arc XL keeps a run of pies consistent behind a 20 mm stone and heavy insulation, which is why it scores 8.4 on heat against 7.6. It also costs around $998.99 and weighs 58.5 lb. For a pizza night now and then, the Koda 16 is the better buy. For a crowd every weekend, the Arc XL is.
What actually differs
-
An even floor
Ooni measured a 360 F swing across the Koda 16's stone. The Arc XL's insulation and 20 mm floor keep pie after pie alike, though one side flame still means turning.
-
Price
Around $498 for the Koda 16 against $998.99 for the Arc XL, and the Arc XL's stand is extra. That gap buys a lot of flour.
-
Weight
The Koda 16 weighs 40.1 lb and folds, so it can travel. The Arc XL weighs 58.5 lb and needs two people to place it.

Heat Performance
Counts for 25% of the scoreOoni Koda 16 7.6Gozney Arc XL 8.4 Better by 0.8Why the Gozney Arc XL scores 8.4Two-layer insulation and a 20 mm cordierite floor keep a run of 16 inch pies consistent, but one side flame now spans a wider stone.
Why the Ooni Koda 16 scores 7.6
A 950 °F ceiling over a big 0.6 in stone, pulled down by the 360 °F swing Ooni itself measured and a slower reheat.

Long-term Reliability
Counts for 20% of the scoreOoni Koda 16 7.7Gozney Arc XL 8.2 Better by 0.5Why the Gozney Arc XL scores 8.2Registering inside 60 days turns a one year term into five, among the longest in this tier; unregistered owners get far less.
Why the Ooni Koda 16 scores 7.7
Five years of cover once registered, but the painted carbon steel shell is meant to live indoors and may fade.
-
Build Quality
Counts for 18% of the scoreOoni Koda 16 8.1Gozney Arc XL 8.6 Better by 0.5Why the Gozney Arc XL scores 8.6Tight seams, a brushed stainless flank and heavy insulation make a shell that feels built for years outdoors, which explains the 58.5 lb.
Why the Ooni Koda 16 scores 8.1
Stainless legs and internal base with a die cast aluminum nose; the plastic feet and dial are the only cheap touches.
-
Ease of Use
Counts for 15% of the scoreOoni Koda 16 7.2 Better by 0.3Gozney Arc XL 6.9Why the Ooni Koda 16 scores 7.2Lighting is a push and a twist, yet the L-shaped flame means turning every pizza, with no thermometer to read the stone.
Why the Gozney Arc XL scores 6.9
Launching a 16 inch pie through a 95 mm slot takes practice, and a 58.5 lb oven seldom moves once placed.
-
Value
Counts for 12% of the scoreOoni Koda 16 8.6 Better by 1.2Gozney Arc XL 7.4Why the Ooni Koda 16 scores 8.6Around $499 buys a 16 inch floor, the price of the 14 inch Koda 2 and well below the $799 Koda 2 Pro.
Why the Gozney Arc XL scores 7.4
Floor costs less per square inch than on the 14 inch Arc, yet around $998.99 still excludes the stand most owners will need.
-
Maintenance
Counts for 10% of the scoreOoni Koda 16 8.8 Better by 0.4Gozney Arc XL 8.4Why the Ooni Koda 16 scores 8.8Propane leaves no ash, and turning the dial up after the last pie burns spills off the stone.
Why the Gozney Arc XL scores 8.4
Spills burn off above 650 F, and the supplied tool lifts the stone out, so a cracked floor becomes a part swap.
