Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Panasonic HomeCHEF NN-CD87KS 4-in-1 comes out ahead by a narrow margin (4.6 vs 4.4). The gap is mostly about Multi-mode cooks who want microwave, convection, broil, and air fry in one countertop appliance and value inverter-smooth power control. — read the strengths below before deciding.

Higher ratedRanked #1 in Best Convection Microwaves

Panasonic HomeCHEF NN-CD87KS 4-in-1

4.6

$499

Panasonic's HomeCHEF combines an inverter microwave, a true 100-425 degrees Fahrenheit convection oven, a FlashXpress broiler, and an air fryer in a 1.2 cu ft countertop footprint. It is the most mode-rich combination unit on the market at this price, and the inverter element lets it simmer and melt without the on-off cycling that defines lesser microwaves. The fan-noise and learning-curve complaints are real but manageable.

Strengths

— Inverter microwave delivers smooth, low-power simmer that conventional magnetron units cannot replicate at sub-30% settings
— Convection bake range from 100 to 425 degrees Fahrenheit covers proofing dough through full roasts in a 1.2 cu ft cavity
— FlashXpress broiler reaches working heat in seconds without preheat, saving meaningful time over the convection element

Watch-outs

— Cooling fan runs for up to six minutes after a cooking cycle ends and is audible across an open kitchen
— Control panel layout has a real learning curve — first-week users routinely miss the combo-mode entry path
— Heating evenness on plain reheats tested only mediocre at Consumer Reports despite the inverter design

Ranked #2 in Best Convection Microwaves

Sharp Carousel SMC1585BS Convection

4.4

$549

Sharp's SMC1585BS is the largest-cavity convection microwave in this guide at 1.5 cu ft and the only model designed from the start to live equally well on a countertop or recessed into cabinetry via the matching trim kit. The 14.1-inch ceramic turntable, 900W microwave, and dedicated Auto Bake, Auto Roast, and Auto Broil presets make it a serious second-oven choice for baking households. The door latch and fingerprints are the friction points.

Strengths

— Built-in capable with optional Sharp RK94S30F (30-inch) or RK94S27F (27-inch) trim kits — the same unit serves countertop and built-in roles
— 1.5 cu ft cavity is the largest in this guide and accommodates a 9-by-13 baking pan with clearance
— 14.1-inch ceramic Carousel turntable spins large casseroles evenly without rim-on-cavity binding

Watch-outs

— Door latch design draws repeated owner complaints — Home Depot reviews flag that the latch button must be pressed firmly before the door will release
— MSRP $779.99 puts the unit in premium-microwave territory when not on sale
— Indicators of trim-kit installation difficulty appear in owner reviews — the 30-inch kit requires a precise cabinet cutout

How they stack up

Panasonic HomeCHEF NN-CD87KS 4-in-1

The NN-CD87KS is the deepest cooking-mode toolkit in this group — five modes versus the Breville BMO870's three and the Toshiba EC042A5C-BS's two. Where the Sharp SMC1585BS gives you more raw oven volume, the Panasonic gives you the inverter for delicate simmer work the Sharp cannot match. If you cook on multiple modes weekly, this is the pick.

Sharp Carousel SMC1585BS Convection

The SMC1585BS offers the largest cavity in this group at 1.5 cu ft — 25% more usable volume than the Panasonic NN-CD87KS or Breville BMO870. It is also the only countertop unit in the guide engineered for built-in installation via factory trim kits, which the Toshiba EC042A5C-BS cannot match. If you need a second oven that can roast a 5 lb chicken, the Sharp gets there with room to spare.
