The air fryer option does a great job on grocery-store frozen veggie spring rolls. A few minutes at 400 and they come out crisp and easy to bite. No more soggy spring rolls.
When I bake muffins, I go for it. My batch usually does about 8 dozen. The convection option lets me bake 4 dozen muffins at a time in 4 pans. They bake evenly on two shelves. Gets me out of the kitchen in less time. And the muffins come out evenly baked, back row to front, left to right. Why did I wait so long.
Also, this oven is 20A power, so I did not have to rewire my house wiring.
