What is the best microwave to buy?

If a countertop, I love the Panasonic inverter models. They are solid, reliable counter micros. If a built-in microwave, GE 5 in 1 units offer so much more than just a micro with speed steam air fry, and convection. For an over-the-range microwave, the LG with the pull-out visor model is a beast. So 3 good options depending on your needs.

Aside from space consideration, do built-in microwaves (microwave/wall oven combo) have better functionalities than a counter-top one? They are a bit expensive but sure look nice on the wall.
