Score: 84/100
Ninja Prestige Smart XL DT551
Score: 81/100Rankings

The Oster 10-Function Air Fryer Oven offers a spacious 25 L capacity and ten versatile cooking functions, highlighted by its double-deck design and high 450 °F temperature. Its internal depth is limited and the unit is relatively heavy, which may affect placement. Ideal for families needing multi-dish cooking on the countertop.

The Ninja Prestige Smart XL offers a 10-in-1 cooking experience with a massive 2.67 cu ft (22 qt) capacity, rapid 90-second preheat, and integrated Pro Cook thermometer for precise results. Its heavyweight, short power cord, and lack of smart connectivity are notable drawbacks. Best suited for large families or households that need a high-capacity, versatile countertop oven.
