Cuisinart are perfectly awesome toaster ovens and even nice convection but their air frying is mostly just ok. I think their budget options are their best stuff since will work just as well and is as reliable as Cuisinart gets.

Ninja has some kind of secret sauce cause their air frying capabilities in their toaster ovens puts single purpose air fryers to shame. Shockingly good but I am always concerned about longevity since seconds from throwing the baby out with the bathwater if they think they have a new device to sell. But these toaster ovens do seem to last. And it’s hard to make them proprietary like other products.

Tl;Dr: if you mostly just care about having a larger more capable air fryer ninja is your answer and they work great. If you want max size the Foodi XL is good and can be got on sale for around the same price as the smaller flip up one but is far more usable as an oven and more.
