This one. I bought the nonstick basket tray, and it's phenomenal. I wish it had come with that instead of the mesh one. https://www.kohls.com/product/prd-7372994/ninja-12-in-1-doublestack-xl-countertop-oven-and-air-fryer-dct601.jsp?skuid=72012821&CID=shopping30&utm_campaign=PREMIUM%20ELECTRICS&utm_medium=CSE&utm_source=google&utm_product=72012821&utm_campaignid=20558767392&CID=shopping30&utm_campaign=KMN&utm_medium=CSE&utm_source=google&utm_campaignid=20558767392&gclsrc=aw.ds&gad_source=1&gad_campaignid=20564910854&gbraid=0AAAAADytpHYK6EbxDULvjdKrxNcGSFn3R&gclid=CjwKCAjwwpDQBhAuEiwAa-4Wo-fgiJnSTfkEPk9SPvVf6cPuE0OKmAF5HxnDxaz9vcFAaAYYpjQ0EhoCmAoQAvD_BwE
We have a Ninja 12-in-1 double oven with FlexDoor. Love it. Our oldest has since moved out, but we were a family of 5, the oldest been a teen boy with a voracious appetite.
We have the Ninja Double Stack XL and love it. We use it more than the oven at this point. We pretty much only use the oven if it's something too big for the air fryer, like a large aluminum roaster.
We love the ninja 12 in 1. We never use our full size oven. Air fries, bakes pizza, deserts, it's honestly flawless. Bake and air fry at the same time. Even replaced our toaster https://www.target.com/p/ninja-1800w-double-stack-xl-countertop-toaster-oven-and-air-fryer-with-smartfinish-38-dualzone-technology-stainless-steel-finish-dct601/-/A-91722292
I'd get a "Ninja Double Door 12-in-1 Countertop Electric Convection Oven & Air Fryer with FLEXDOOR" I was gifted one and thought it would be lame. Boy was I wrong. We barely use our main oven anymore unless we're making a large roast or something that won't fit in the mini oven. Wait for a sale.
We have a Ninja Double Stack XL Countertop Oven and Air Fryer. They cost about $300. Just my wife and I in the house. We love it. About the only time we use our regular oven is when we are making cornbread in a cast iron skillet or baking a big pizza.
I've got the Ninja dual oven with the little bitty top door you can open separately. I like it a lot.
The Ninja double stack XL was really big, it took up a lot of counter space I didn’t have. I ended up selling it and getting the Crispi Pro, which I love and it doesn’t take up my entire counter. I can’t speak to the Cosori, but I do really like the Crispi Pro. Seems easier to clean as well
