You're suppose to place dish offset from centre for better heating, imo makes big difference. Of course you're already doing that by stuffing containers off centre, but spinning turntable + right power levels (instead of just nuking 100%) makes big difference for reheating. I have breville 3in1, you can turn off the turntable rotation.

Another comment mentioned commercial microwaves, especially larger ones with multiple magenetrons so need to spin. But they're loud. But easier to clean.
