The Breville Smart Oven Air Fryer Pro is a 13-in-1 countertop convection oven with a massive 1 cu ft interior and high-temperature capability up to 249 °C. Its size, weight and hot exterior make it unsuitable for compact spaces. Ideal for serious home cooks who need a full-size oven replacement with air-fry functionality.

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.
