Comparing the Oster French Door Digital Convection Toaster Oven (TSSTTVFDDG) to the Cosori Air Fryer Toaster Oven (CO130-AO) shows that size isn’t everything. The match is one-sided to say the least, but it does bring out the advantages that made the Cosori our definitive best-to-buy pick.

In terms of design, the Oster has a larger cooking chamber and an aesthetic french door, but that’s about it. It has less nichrome heating elements, less powerful convection system, less tray positions, and less accessories than the Cosori.

Usability-wise, the Cosori has a more informative digital display, better responsive buttons, more toggle switches, and an actually precise automatic preheat phase. To top it all off, the Cosori is cheaper than the Oster as well.

With all the stated advantages, it’s no surprise that the Cosori excelled at all of our cooking tests, including toasting bread, baking pizza, roasting a whole chicken, and air frying fries. Meanwhile, the Oster is only above average in three of them and lower in the fries test.
