convection ovens/air fryers are usually an upgrade flavor wise vs microwaves. you put in similarish amount of effort into “cooking” with them but air fryers usually will taste better at the cost it takes a bit longer. they are smaller so they dont take as long to heat up as a traditional oven, which is really standard ovens biggest weakness.

basket style air fryers imo are more convenient if youre heating something that needs to be shaken or moved around after a bit, usually a lot of fried stuff vs a convection oven that uses a tray.
