Toaster oven should be a lot less efficient and slower because it's heating up a larger space, but the result should be the same.

I can melt cheese over bread or bagel in a toaster oven.

Yeah, that’s one thing I discovered when I stopped using a slice toaster. I can put a cold pat of butter on the bread about halfway through the toasting process, and avoid the trauma of trying to spread cold butter on the toast.

The hack is to turn the empty toaster on and lay the toast flat on top. Good way to reheat pizza w/o oven.

It might be a cultural thing but a slice toaster is way more of a set and forget operation, which I like... also, a toaster gets based used for one thing and a toaster oven is used for a lot of other foods, and I have to worry about cross contamination.

Oh that makes sense. I use mine 80% for toast and the remaining use is usually bread-adjacent things.

If I was also using it to heat up chicken tikka masala or something, then that would probably not be good.
