I just bought a Ninja one for $250 from Costco. So far, it is fine. I made brownies in it and cinnamon rolls but have not baked bread in it.

I have the Ninja 101, which is one which folds upright on the countertop. I dont find that the air fry feature works as well as a stand alone air fryer, but all the other modes work well. It makes great toast, air broil and bake are great and many weeks can go by before I need to turn on my ”real” oven. I've made banana bread and salmon in there; any regular baking dish will work as long as it fits.

If I were to replace it today, I would move up to the 300 level, while that model doesn’t fold up on the counter, it has more height space so you can more easily bake a spatchcocked chicken, or use pans with taller sides.

I did my research and the Breville wins.

If you need a bigger version, just go with the Pro version.

We have the Breville Smart Oven Pro and love it. It fits a 1/4 sheet pan. It can toast up to 6 pieces of bread or bagels and does a really good job. It does a great job with brownies and cookie bars. We reheat things in it. We use the broiler as well. It can fit a frozen pizza. We have a separate air fryer… the Ninja dual zone.

We have 2 Brevilles and have never had a problem with either door or the stainless steel.

I've had a Breville Smart Oven for 15 years and it's still going alone with its tasks. I'll replace it with another Breville when the time comes.

I have the top of the line ( as of 2018) Breville. I love everything about it. I have owned this one for six years (and the previous Breville for many years). I take it to the back covered patio during the hot days of summer to use and to keep the heat out of the house.

I have a Breville smart oven and love it! It is a convection oven, but doesn't really air fry (IMO), and it's lousy for making toast -- but it's an awesome countertop oven. I only use my regular oven for large things that won't fit in the Breville.

I have the largest Cuisinart, the one with the rounded back to fit a 13" pizza. Works great, fits a 1/4 sheet pan. I've baked cookies, pies, and cake layers successfully. When summer hits we just don't cook meals that can't fit in the toaster oven. Like the Breville, it's not great at toast--very slow. That seems to be a universal issue though. The larger the toaster oven, the worse it is as a toaster.

When it dies, I might get the Breville. The Cuisinart has an annoying VERY bright blue LCD screen that never turns off.

That is annoying - I have a humidifier like that, and it would bother me at night (it's in my bedroom)......I had to put a double layer of duct tape over it.
