Verdict: These products serve fundamentally different purposes—one is a large countertop unit and the other an over-the-range model with venting—so direct comparison is limited. Panasonic NN-SN966S leads on capacity and power per typical microwave reviews from RTINGS and Consumer Reports. Whirlpool WMH31017HZ suits range installations but trails in raw cooking specs.
