Our Verdict
LG NeoChef MSER2090S
Panasonic NN-SF57RM
The LG NeoChef MSER2090S and Panasonic NN-SF57RM suit different uses. The LG's cooking chamber is twice the size, all the better for accommodating larger dishes, and can heat food slightly faster at its maximum power setting, though in the real world, this difference isn't especially relevant. Meanwhile, the Panasonic model's far more compact design makes it a better option for space-limited kitchens, and its flatbed cooking chamber is easier to clean.
