Our Verdict

Panasonic NN-SN975S

Panasonic NN-SN68QB

The Panasonic NN-SN975S is a better microwave than the Panasonic NN-SN68QB for most people. They're both powerful options that cook quickly, and they both include cooking sensors for more hands-off cooking, but the NN-SN975S is easier and more pleasant to use. It has physical buttons, which are more responsive than the NN-SN68QB's membrane touch panel, and it includes buttons to mute or lock the controls. The NN-SN975S also has a larger internal capacity, so you can use it to heat up larger items, like a full casserole, but it takes up more space on your counter, too. The NN-SN68QB is quieter, so you may prefer it if noise is a priority for you or if you're short on space.
