I imagine foods that need a lot of moisture content are probably better with the microwave, those trays probably wouldn't seal well and you could lose a lot of moisture in the 30min or so it probably takes to reheat from frozen. But in the other direction it seems foods that are crispier usually aren't great in the microwave in comparison. But IME even with a good microwave a lot of frozen meals tend to reheat somewhat unevenly with the default directions even with a rotating tray. I do admit I've never used a microwave where the magnetron moves though.
