The catch
Ooni Karu 2 Pro
Flexibility with solid fuel means handling fuel and ash.
Side by side
Karu 2 Pro is for you if you plan to switch between wood, charcoal and gas, or use its connected food-probe readings. The gas burner comes with the selected Essentials bundle. Arc XL is for a propane-focused 16-inch setup with a low body and a digital thermometer. Each reaches a stated 950°F and fits 16-inch pizza.
Before you buy
A different fuel routine is possible with Karu 2 Pro, and this exact Amazon Essentials bundle already includes the gas burner attachment. Arc XL stays focused on propane. Go with Karu when cooking over solid fuel is an activity you want to take on, since switching fuel brings extra setup, handling and care for cooled ash. Owning the option alone is a weak reason.
Where this comes from
The comparison is between supported fuel systems and what the selected package contains. It makes no claim that one fuel gives a preferred flavor, and it does not suggest changing fuel while the oven is hot.
The catch
Flexibility with solid fuel means handling fuel and ash.
The catch
Wood and charcoal are ruled out.

The Karu 2 Pro Essentials bundle and Arc XL are compared on fuel changes, 16-inch pizza, temperature monitoring and installation space.
This one comes down to rated pizza size and fuel first, then to the limits of your own setup.
Which one fits
Wood and charcoal work on Karu, and this selected bundle includes a gas burner.
Arc XL is built for propane alone.
Food-probe and ambient temperatures are reported by Karu's hub.
The rated pizza size for each is 16 inches.
In practice
A different fuel routine is possible with Karu 2 Pro, and this exact Amazon Essentials bundle already includes the gas burner attachment. Arc XL stays focused on propane. Go with Karu when cooking over solid fuel is an activity you want to take on, since switching fuel brings extra setup, handling and care for cooled ash. Owning the option alone is a weak reason.
The comparison is between supported fuel systems and what the selected package contains. It makes no claim that one fuel gives a preferred flavor, and it does not suggest changing fuel while the oven is hot.
A 16-inch pizza fits in both ovens, yet Karu's overall height of 32.4 inches includes a chimney, whereas Arc XL's body is 13.5 inches high. Arc can suit a lower visual profile and a different storage plan. Neither height gives approval for putting either oven under an overhang or in an enclosed counter installation.
Published body heights differ by 18.9 inches. The combustible clearances and ventilation that are required come on top of the body dimensions.
Through Bluetooth, Karu's hub can report ambient and food-probe temperatures. That helps when a roast follows pizza, but it does not turn a wood fire into a thermostat-controlled indoor oven. For its propane routine, Arc has a digital temperature display that gives local information.
This conclusion comes from the contrast between temperature sensing and manual fuel control. Neither source establishes a guarantee of automatic cooking outcomes.

Ooni, 16-inch multi-fuel essentials bundle
Built for pizza and roasting, this tall, roomy live-fire oven has a 17-inch floor, a big glass door and a connected temperature hub.

Gozney, GAPBNUS1624 Bone
Propane-fired and sized for 16-inch pizza, this oven has a rolling side flame, a digital temperature display and a removable 20-millimeter stone.
Spec by spec
| Spec | Ooni Karu 2 Pro | Gozney Arc XL | In practice |
|---|---|---|---|
| Rated pizza size | 16 inches on a 17-inch cooking surface | 16 inches | A 17-inch pizza rating does not follow from Karu's larger quoted floor. |
| Fuel | Wood, charcoal or included gas-burner attachment in selected bundle | Propane | A different setup and cleanup routine comes with fuel flexibility. |
| Maximum temperature | 950°F | 950°F | No advantage in temperature ceiling has been shown. |
| Temperature information | Bluetooth hub with ambient and food-probe readings | Digital thermometer | What Karu adds is food-probe and connected monitoring and not automatic fire management. |
| Body height | 32.4 inches including chimney | 13.5 inches | Planning for placement and storage is affected by the chimney. |
| Stone thickness | 15 mm | 20 mm removable stone | Thickness by itself does not show measured recovery. |
| Included launch tool | 14-inch perforated peel in selected Essentials bundle | No peel in standard listed box | Check if your intended pizza size calls for a separate tool. |
Trade-offs
Change of plan
Go with Ooni Karu 2 Pro. Both work on Karu, and the selected bundle supplies gas as well.
Go with Gozney Arc XL. That narrower setup suits Arc XL.
Decision guide
Pick Karu 2 Pro if switching between wood, charcoal and gas will really happen, or if you will use its connected food-probe readings. The selected Essentials bundle includes the gas burner. Pick Arc XL for a 16-inch setup focused on propane, with a low body and digital thermometer. Both reach a stated 950°F and fit 16-inch pizza.
Karu's flexibility pays off for an owner who likes managing wood or charcoal along with gas. Someone who will always switch on propane may find Arc's focused arrangement easier to plan around. With the Karu bundle you skip a separate burner purchase, but the work of running solid fuel does not go away.
Karu's chimney is part of its working shape, and Arc's broad body has its own depth and width. Leave room for turning pizzas, handling fuel and following the manuals. Never read a lower body as permission to cut the required distance to combustible structures.
Each is a 16-inch pizza oven with a stated maximum of 950°F. Karu's 17-inch floor and Arc's thicker stone describe how the ovens are built and do not point to a measured throughput winner. Size your largest pizza and cookware to the real opening and the permitted accessories. The biggest number in the marketing copy is the wrong guide.
