Build Quality
Overall Design Scoring

The Cuisinart TOB-40N has a simple design but with some nice attention to detail. To accommodate its spacious interior, the oven uses 1800 W.

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

Usability Comparison

User Control
Ease of Use
Overall Usability Scoring

The Cuisinart TOB-40N doesn’t offer much in terms of ease of use. While the control panel is simple, not having a timer means you’ll need an external timer when using this oven. The oven posed no difficulties in cleaning but nothing to help either.

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.

Overall Performance Scoring

The Cuisinart TOB-40N performed well in making toast and whole roasted chicken despite not having a convection system. However, the lack of convection resulted in uneven surface colors on our test dishes.

Even though the oven runs on 1800 W, it wasn’t able to produce a good result in baking french fries. This made the oven pale in comparison to our top picks.

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 Cuisinart TOB-40N and the Black+Decker CTO6335S were worthy adversaries every step of the way. Performance-wise, the Black+Decker won out at baking pizza, french fries, and roasting a whole chicken while the Cuisinart only scored better at making toast. Nonetheless, the actual scores were only marginally different with the edge going to the Black+Decker.

The Cuisinart and the Black+Decker both have 4 heating elements but the former’s are nichrome while the latter’s are quartz. Although the Cuisinart has a higher power rating — 1800 W compared to 1500 W, it doesn’t have a convection system like the Black+Decker.

Both ovens are built sturdy and include slide-out crumb trays, but the Black+Decker stands out with its tamper-resistant casing. Despite having a large cooking chamber for its size category, the Cuisinart just can’t compete with an actual large-sized unit. In addition, the Black+Decker’s various cooking functions and broiling rack can be extra helpful to beginner homecooks.

The easy-grip dials of the Cuisinart are more reliable than its competitor’s buttons though. With the ovens’ similar prices, the Cuisinart’s auto-slide rack and its customized stay-on feature might just win you over.
