The catch
Breville Smart Oven Air Fryer Pro
With a 21.4-inch body width and required ventilation, it needs a counter spot picked in advance.
Side by side
Breville BOV900 vs Ninja DCT601: Breville gives tall food one large space, Ninja keeps temperatures separate
Quick verdict
For large pans and tall food, get the BOV900. If two dishes need different temperatures and a coordinated finish, the DCT601 is the more useful oven.
Before you buy
Why, and what it costs you
Two temperature paths, each independent
With DCT601, the count of separately controlled cavities doubles.
Where this comes from
2 / 1 = 2 cavities. Usable cooking volume does not double.
The catch
Ninja Double Stack XL Countertop Oven and Air Fryer
The current US product specification gives a 33.07-pound body, so you need a stable counter and the ventilation space named in the manual.

In practice
Differences you will notice
Two temperature paths, each independent
With DCT601, the count of separately controlled cavities doubles.
How we worked this out
2 / 1 = 2 cavities. Usable cooking volume does not double.
Tall food may not fit in a divided cavity
A tall item that will not go into either Ninja chamber may fit in Breville.
How we worked this out
Two vertically divided chambers set against one uninterrupted cavity.
One planning task goes away with Sync
Ninja can line up when different settings finish.
How we worked this out
Both independent ovens are coordinated by Smart Finish. With Breville, you plan the start times by hand.

Spec by spec
Where they really differ
| Spec | Breville Smart Oven Air Fryer Pro | Ninja Double Stack XL Countertop Oven and Air Fryer | In practice |
|---|---|---|---|
| Cooking chambers | 1 | 2 independent ovens | Separate temperature routines are supported on Ninja. |
| Finish coordination | Manual scheduling | Smart Finish | Two cooking endpoints can be coordinated by Ninja. |
| Large pan guidance | Most 9 by 13-inch pans | Separate upper and lower chambers | Judge each Ninja chamber on its own and set the size of the whole appliance aside. |
| Cooking modes | 13 | 12 | Different cavity arrangements are behind the counts. |
Trade-offs
What each pick costs you
With Breville Smart Oven Air Fryer Pro

When the answer changes
A main and a side call for different temperatures simultaneously
Go with Ninja Double Stack XL Countertop Oven and Air Fryer. Two ovens, each controlled independently, come with Ninja.

Two foods done at the same time
Go with Ninja Double Stack XL Countertop Oven and Air Fryer. Smart Finish handles the coordination automatically on Ninja.
One large vessel for roasting
Go with Breville Smart Oven Air Fryer Pro. Each Ninja chamber has to be checked on its own for the vessel, whereas BOV900 offers one larger uninterrupted cavity.
Decision guide
How to decide
Large pans and tall food suit the BOV900. Two dishes that need different temperatures and a coordinated finish make the DCT601 the more useful oven.
Two racks cannot cover two temperatures
Both racks in Breville’s single cavity get the same oven environment. Ninja divides the appliance into two independent ovens, so a main dish and a side can run on different settings.
Splitting the oven alters what fits
Each Ninja chamber is shorter than a large uninterrupted oven. Because of that, a tall covered dish can point you to Breville, even though the Ninja as a whole looks substantial.
What you gain is matched timing
The two Ninja ovens are scheduled by Smart Finish to finish together. That cuts down on staggering things by hand, but different foods still need suitable settings of their own and doneness checks.
What this page can’t tell you

By the numbers
What the data shows
What we found across the countertop ovens we compare, plus the checked facts behind each finding.
How many fit
None of the 26 models checked meets all of “Cook two foods, each at its own setting”, “A 9 by 13-inch pan fits”, and “Big enough for meals sized for a family”, so the pick goes to the closest practical compromise.
