Between the Black+Decker Convection Toaster Oven (CTO6335S) and the Cosori Air Fryer Toaster Oven (CO130-AO), the latter—as our definitive best-to-buy pick wins by a landslide across all fronts. Nonetheless, the former still put up a good fight as our best budget pick.

Both are large digital toaster ovens with internal lighting and convection which usually cost more than their analog conventional counterparts. However, the Black+Decker is one of the cheapest units in the large category.

The Cosori is more expensive but it offers tremendous value in return. The Cosori has a more informative digital display, better responsive buttons, more toggle switches, an actually precise automatic preheat phase, and more accessories.

To top it all off, the Cosori has a higher power output to excel at all of our cooking tests, including toasting bread, baking pizza, roasting a whole chicken, and air-frying fries. Nonetheless, the Black+Decker delivered a solid performance, getting above average in all of the tests.
