The type of Microwave you need depends on the type of use you want to get for the microwave. For reheating food, or preparing snacks and popcorn, there would entirely a different microwave. If you are planning to use Microwave in place of Oven, then an advanced form of Microwave is required. For making popcorn, or reheating leftovers, a different less powerful with less onboard features will get the job done.
