The best is kind of tough, as there are some really good units out there but when you add a trim kit to the equation this unit from LG with inverter technology, led lighting inside to make the unit nice and bright, easy-clean interior, and a 6 point turntable for sturdiness. It kind of stands alone, they do make a 30″ trim kit for it. The unit has a quick start every press is 30 seconds at high power. It’s a great microwave!
