Our Verdict

Sharp SMC2266KS

Panasonic NN-SN975S

The Sharp SMC2266KS and the Panasonic NN-SN975S are both large, powerful microwaves, and you may prefer either. Both options offer simple operation for day-to-day use, with a few minor differences. The Panasonic has physical buttons, which are more responsive than the Sharp's membrane touch panel, but they can also be harder to clean. With the Sharp, it's easier to start simple cooking tasks, but the Panasonic makes it easier to adjust the power or set a specific cook time. The Sharp makes less noise during operation.
