Does it really air fry as well as a dedicated air fryer?

It air fries in the microwave cavity, so batches are smaller than a basket-style air fryer. Results are close for fries, nuggets and vegetables, but a dedicated unit handles larger loads.

Can it be built in above a wall oven?

Yes, with the additional 30-inch flush trim kit. Without the kit it sits on the counter like any microwave.

How much microwave power does it have?

Up to 1200 watts of microwave energy, which is on the high side for a countertop unit and reheats and defrosts quickly.

What can the convection mode do?

It convect bakes and roasts like a small oven, so you can do cookies, casseroles and roasted vegetables. Expect smaller capacity than a full wall oven.

Is it worth it over a plain microwave?

If you would otherwise buy a separate air fryer or toaster oven, the 3-in-1 design saves space and outlets. If you only reheat and defrost, a simple microwave does the job for less.
