Our Verdict

Panasonic NN-CD87KS

Panasonic NN-CD66NS

The Panasonic NN-CD87KS is better than the Panasonic NN-CD66NS for most people. Both are medium-sized, high-end multifunction microwaves that can also air fry and broil. The NN-CD87KS is a little more compact but has a bigger cooking chamber, especially in terms of vertical space. It's faster, and its controls are easier to use. That said, if noise level is a priority, you might prefer the much quieter NN-CD66NS. The NN-CD66NS also has 10 microwave power levels while the NN-CD87KS has only seven.
