Our Verdict

Ninja Foodi DZ401

Ninja Foodi DZ550

The Ninja Foodi DZ401 and the Ninja Foodi DZ550 are both great options, but the DZ550 is a slightly better option. Its biggest advantage is in frying quality; the DZ550 leaves more of your food crispy and well-browned. It also preheats and cooks slightly faster, and it's more versatile. That said, it's also the more expensive option, but not by much, so the difference will be worth it for most people.
