Build Quality
Overall Design Scoring

The Black+Decker CTO6335S has a sturdy construction. Standouts for us were the baking pan plus broiling rack combo and the quartz heating elements.

The Cosori CO130-AO has a lot of design features, all of which are of high build quality. A few that stood out to us were the clear LED display, powerful convection system, large cooking space, high power output, and handy accessories like the rotisserie kit and air fryer basket. If we were trying to be nitpicky, we’d say the interior can be improved with a non-stick coating like the Breville BOV845BSS.

Usability Comparison

User Control
Ease of Use
Overall Usability Scoring

The Black+Decker CTO6335S has an easy-to-use control panel. However, it doesn’t have any features that encompass convenience. Even the automatic preheat feature isn’t very useful. In addition, its door and buttons are a bit dodgy.

A well-designed automatic preheat phase, simple toggle options, and practical cooking functions gave the Cosori CO130-AO a good score. The cooking chamber as well as accessories could have better coatings to make them easier to clean, though. As an additional minor inconvenience, the oven doesn’t have a pause-resume mechanism upon opening and closing the oven door.

Overall Performance Scoring

The Black+Decker CTO6335S performed quite well in most of our test dishes except for the baked french fries. We speculated that 1500 W wasn’t able to heat the elements fast enough to keep up with the oven’s large capacity.

The Cosori CO130-AO, on average, performed great throughout all of our tests. It made full use of its high power output of 1800 W and its powerful convection system. To us, these were some of the main grounds for establishing the product’s value for the money. The included rotisserie kit and air fryer basket were also very helpful in our Whole Roasted Chicken and Baked French Fries tests, respectively.

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.
