Our Verdict

LG NeoChef MSER2090S

Panasonic NN-SN68QB

The LG NeoChef MSER2090S is a better microwave than the Panasonic NN-SN68QB for most people. They're both powerful models that heat food quickly, but the LG offers a larger internal capacity and is easier and more convenient to use day to day. It has a glass touch panel which is more responsive than the Panasonic's membrane touch panel. While it's easy to start simple cooking tasks, like heating for three minutes at full power, on either, the LG makes it a little easier to adjust the power or set a more specific cook time. That said, the Panasonic is quieter, which you may prefer if noise is a concern.
