The Black+Decker (CTO6335S) and the Oster French Door (TSSTTVFDDG) are both large convection toaster ovens, only the latter is slightly larger. Their scores resemble one another quite a lot, so the winner comes down to the most minute details.

Design and usability-wise, both products have a thick casing, an interior light, and a limited digital control panel. The Oster stands out a bit more with its single-pull French door. However, its flat buttons are not as responsive as the Black+Decker’s raised ones.

Performance was the deciding factor for the Black+Decker’s victory. Despite its lower power output, the Black+Decker has higher scores in almost all of the tests, including toasting bread, baking pizza, and fries. It only scored slightly lower than the Oster in roasting whole chicken.

The Black+Decker’s good performance scores and cheap price were the main reasons why we chose it as our pick for the best budget toaster oven. As for the Oster, we suspected that its cooking chamber was too large for its power.
