How to choose
Capacity for large dishes
Start with the cooking space, since a built-in microwave is fixed in place once installed. The Frigidaire gives 2.2 cu. ft. and fits large dishes and multiple items at once, while the KoolMore and Sharp drawers give 1.2 cu. ft. and the Summit gives 0.9 cu. ft. Check the width of your opening too: the Frigidaire cutout is 24 3/4 inches wide, and the Summit fits 24-inch openings.
Drawers versus a built-in oven
A drawer pulls out low in the cabinetry, while a built-in oven sits at a fixed height in the wall. The KoolMore drawer opens with one touch and closes slowly, and the Sharp drawer opens smoothly with a hands-free close. The Frigidaire and Summit are built-in ovens rather than drawers, so pick the form that suits how you load dishes.
Programs, sensors and power levels
Programs do the choosing for you, while power levels let you set the strength yourself. The Frigidaire has 3 programs with sensors that set power levels and cook time, and the KoolMore has 10 custom cooking levels with 10 power levels. The Sharp has 3 programs with 10 power levels, and the Summit has 5 programs with settings for popcorn, pizza and beverages.
