The Breville Smart Oven Air Fryer Pro wins this 2026 comparison because of its massive interior and dual-speed convection fan. While the Ninja SP101 preheats faster, its restrictive three-inch height limits you to flat foods. The Breville fits whole roasts, justifying the higher price tag.
\n\n\n\nI tested both ovens side-by-side over three weeks, making everything from frozen fries to whole chickens. Choosing between these two comes down to your kitchen layout and what you cook most often. One functions as a rapid meal station, while the other completely replaces your traditional wall oven.

Ninja SP101 Digital Air Fryer Toaster Oven
\n\n\n\nIn our testing, the 1800-watt Ninja SP101 operated as a remarkably fast cooking appliance. The machine features a literal 60-second preheat, meaning I had sheet pan meals sizzling before the Breville even reached 350 degrees. The defining constraint is the interior ceiling. At exactly three inches tall, I physically could not fit a standard whole chicken inside. You are restricted to butterflied meats, 13-inch pizzas, nine slices of toast, or standard flat air-frying tasks.
\n\n\n\nBreville BOV900BSS Smart Oven Air Fryer Pro
\n\n\n\nThe Breville BOV900BSS feels like a scaled-down commercial oven. I ran a batch of dehydrating apples across four separate trays at once, and the Element iQ system kept the temperature exact without requiring me to rotate the racks. This unit uses PID (Proportional-Integral-Derivative) control—a digital algorithm that senses temperature drops and steers power to specific quartz heating elements to eliminate cold spots. The super convection setting pushed enough air to crisp two pounds of fries in 18 minutes, but you pay for this power with a heavy, permanent countertop footprint.
\n\n\n\nHead-to-Head
\n\n\n\nCooking Capacity & Versatility — Breville BOV900BSS Smart Oven Air Fryer Pro wins
\n\n\n\nThe Breville dwarfs the Ninja in vertical space. While the Ninja limits you to 13-inch pizzas or flat sheet meals, the Breville handles whole turkeys and proofs bread dough, giving you 13 specialized functions versus the Ninja’s eight.
\n\n\n\nSpeed and Preheating — Ninja SP101 Digital Air Fryer Toaster Oven wins
\n\n\n\nThe Ninja excels at immediate tasks. I clocked its preheat time at exactly 60 seconds, allowing me to start cooking frozen foods almost instantly. The Breville requires a standard 5-to-7 minute warmup.
\n\n\n\nTemperature Precision — Breville BOV900BSS Smart Oven Air Fryer Pro wins
\n\n\n\nBreville utilizes PID digital control to maintain exact temperatures without fluctuations across its five quartz elements. In our testing, the Ninja ran slightly hot on the bake setting, scorching the outer edges of sugar cookies.
\n\n\n\nAir Frying Performance — Tie
\n\n\n\nBoth machines produce deep-fried textures using less oil. The Breville uses a super convection fan to push a massive volume of air, but the Ninja’s shallow depth forces heat directly over the food for an equally crisp finish.
\n\n\n\nMulti-Batch Cooking — Breville BOV900BSS Smart Oven Air Fryer Pro wins
\n\n\n\nThe Breville allows you to stack up to four trays simultaneously for dehydrating or air frying family-sized batches. The Ninja restricts you to a single flat pan, forcing you to cook in consecutive rounds for larger groups.
\n\n\n\nBuy Ninja SP101 Digital Air Fryer Toaster Oven if…
\n\n\n\nYou routinely cook sheet pan dinners, frozen snacks, or flat cuts of meat after work and hate waiting for an oven to preheat. If your meals primarily consist of chicken breasts, asparagus, and pizzas, the three-inch interior height limit will never bother you.
\n\n\n\nBuy Breville BOV900BSS Smart Oven Air Fryer Pro if…
\n\n\n\nYou want an appliance to completely replace your wall oven for Thanksgiving sides, slow-cooked stews, and heavy baking. If you regularly roast whole chickens or bake artisanal bread requiring proofing environments, this machine provides the vertical space and temperature stability required.
\n\n\n\nOur Verdict: Breville BOV900BSS Smart Oven Air Fryer Pro
\nThe Breville Smart Oven Air Fryer Pro is the clear winner for anyone seeking a true primary oven replacement. Its five independent quartz heating elements and massive vertical capacity unlock slow cooking, proofing, and tall roasting—tasks the Ninja SP101 physically cannot perform due to its shallow build.\n\nBuy the Ninja if your dinner routine relies on speed and flat foods. Otherwise, the Breville justifies its higher price tag by handling every culinary task a traditional oven can, but with faster air-frying times and zero cold spots.
