Consumer Reports listed the Panasonic Genius Prestige NN-SD297[SR] as its top-ranked over-the-range microwave in an October 2013 report, while ConsumerSearch.com listed the GE Profile PVM9179SFSS as its top choice in October 2014. Amazon.com reviewers give the microwaves 3.9 and 3.2 out of five stars respectively, as of February 2015.
The Panasonic unit is the best at venting, according to Consumer Reports. Other positive aspects include a wire rack for cooking two foods simultaneously, 1,200 watts of cooking power and a sensor-based cook function that bases the power and time on the food placed in the microwave. One reviewer noted that the microwave cooked food evenly, especially when the sensor cook function was used. Consumer Reports noted that the unit is noisier than other microwaves, and a reviewer on Amazon.com also noted excessive noise.
Consumer Search praises the GE unit for its size, 1,000 watts of cooking power and convection feature that allows it to be used as a convection oven. Reviewers on Amazon.com mentioned how quickly the unit cooks food, its design and the quiet range vent fan. Common complaints include the learning curve associated with the unit and the button layout, as certain features such as the timer require multiple button presses.
