Comparisons
Air frying against the alternatives, and against itself: oven, microwave, your oven\u2019s air-fry mode, and the choice between one basket and two. Each one reaches a conclusion only where the sourced facts support one.
Air fryer versus oven
Faster and cheaper to run for small quantities; no advantage at all for a full tray, and worse at several things.
Single basket or dual zone?
Two drawers buy you independence, not capacity. Whether that is worth the worktop depends on whether your problem is quantity or variety.
Basket or oven style?
A drawer crisps harder and holds less. An oven-style cavity holds more, sees the food, and asks you to think about shelves.
Air fryer or microwave?
They heat food by unrelated mechanisms and are bad at opposite things. This is not a choice between two appliances so much as a rule for which to reach for.
Your oven's air-fry mode versus a real air fryer
It narrows the gap and does not close it, and the reason is the size of the cavity rather than anything the manufacturer did wrong.
