The larger convection/toaster ovens (that have an air fryer setting) are amazing. I had to replace an ancient toaster oven, was curious about air fryers, and the Cuisinart TOA-60 not only replaced the toaster oven, but I hardly now ever use my standard oven. Fries (chips) made from raw potatoes come out wonderfully brown and crispy in about 25 minutes - I've never parboiled them. Toast is preternaturally uniform. Chicken thighs roast/fry amazingly. Small casseroles, roasted veggies, small batches of cookies - all come our great. But the reason is it's got room for stuff to cook - the tray/rack size is 12" x 10". I can't imagine those little upright ones with a 5-6" diameter basket are good for anything other than crisping up a half dozen frozen chicken nuggets.
