Convection toaster ovens have been around for a long time, but for the most part have been “toaster oven plus a little fan.” Air fryers showed up with an emphasis on I’M BLOWING ALLLLL THE HOT AIR!!! I’ll make frozen mini pizzas in my air fryer and have to stab the pepperoni with toothpicks or they end up God knows where lol.
I have both, but would be willing to just have the toaster oven version if it stepped up its blowing game. Until the day comes when one of the appliances craps out on me, I’ll use both.
