Our Verdict

Ninja Foodi DZ401

Breville the Joule Oven Air Fryer Pro

The Ninja Foodi DZ401 is a better air fryer for most people than the Breville the Joule Oven Air Fryer Pro. Both appliances make decent-quality fried food and offer excellent versatility, but the Ninja preheats faster, cooks faster, and maintains a more stable temperature throughout the process. It also takes up less counter space. On the other hand, the Breville offers more capacity and more cooking surface area, so if you're making food for a crowd, you may prefer it. The Breville has some additional settings that are only available through their companion app, like 'Autopilot,' which automatically switches between cooking modes based on your recipe selection. You may find these features to be a benefit or drawback depending on whether you prefer to have assistance through guided recipes or full control over the cooking process.
