Our Verdict
Toshiba ML-EC42P(SS)
Panasonic NN-SF57RM
The Panasonic NN-SF57RM and Toshiba ML-EC42P(SS) each have their own advantages. The Panasonic has a noticeably narrower, shallower footprint, making it an easier fit in kitchens where space is at a premium. It also heats food slightly faster at maximum power. That said, the Toshiba has a slightly more spacious cooking chamber and runs a little quieter while in use.
