The Panasonic NN-SN686S is the stronger default if you care about faster cooking, inverter-style power control, and gentler defrosting. The Toshiba EM131A5C-BS still makes sense if you prefer a handle door, a larger listed turntable, mute mode, and simpler sensor presets.

Both are 1.2-cubic-foot countertop microwaves, but they are not the same kind of appliance decision. Panasonic leans into cooking control; Toshiba leans into familiar controls, a handle, and convenience modes.
The Panasonic wins because its 1200-watt output and inverter approach give it the stronger cooking-control story for reheating leftovers, softening ingredients, and defrosting without relying only on full-power bursts. That matters more over years of daily use than one extra shortcut label.
Choose the Toshiba EM131A5C-BS if your kitchen routine values a pull handle, smart-sensor menus, a larger listed glass turntable, mute mode, and ECO mode more than Panasonic's inverter-focused cooking control.
The NN-SN686S is a 1.2-cubic-foot countertop microwave with 1200 watts of cooking power, Panasonic inverter cooking, Genius Sensor controls, Turbo Defrost, and a 13.4-inch turntable.
The EM131A5C-BS is a 1.2-cubic-foot countertop microwave with 1100 watts of cooking power, smart-sensor menus, ten power levels, a 12.4-inch turntable, mute mode, and ECO mode.
A countertop microwave is an everyday appliance. The right pick depends less on a spec-sheet win and more on how you reheat plates, defrost ingredients, and interact with the door and controls.
The Panasonic's 1200-watt rating gives it more heating headroom than the Toshiba's 1100-watt rating. In practice, that matters most for dense leftovers, large bowls, and repeated daily use.
Inverter-style control is useful when you want gentler cooking or defrosting. If your microwave mostly heats mugs and popcorn, the benefit may be less visible.
A handle can feel better when hands are full or the microwave sits below eye level. A push-button door can still be fine, but it is worth choosing deliberately.
Panasonic is the cooking-control pick. Toshiba is the handle-door and simple-sensor alternative.

We focused on specs that change daily ownership: cooking power, heat-control approach, turntable size, door style, sensor controls, counter fit, and noise-related convenience settings.
We gave extra weight to wattage, inverter-style power delivery, sensor cooking, and defrost behavior because those details affect how often leftovers dry out or frozen food stays cold in the middle.
We compared capacity and turntable diameter, then treated door style and counter depth as ownership details rather than afterthoughts.
We did not use live pricing, ratings, review counts, coupons, or availability. The recommendation is based on stable model features and shopper fit.
Specs were checked against manufacturer model information and product-specific retailer pages. Prices, ratings, review counts, coupons, and live availability were intentionally left out.

The right microwave is mostly about reheating behavior, door style, counter fit, and whether inverter control is worth prioritizing.
Panasonic NN-SN686S is the stronger default if you want 1200 watts, inverter-style power delivery, Genius Sensor cooking, and a compact 1.2-cubic-foot footprint for everyday reheating and defrosting.
Choose the Toshiba if you want a 1.2-cubic-foot microwave with 1100 watts, a handle door, mute mode, ECO mode, and straightforward smart-sensor menus.
It can. Panasonic uses inverter power control to avoid relying only on full-power pulses, which is useful for gentler reheating, defrosting, and foods that dry out easily.
No. Both are countertop microwaves. Measure counter depth, side and rear clearance, door swing, and access to a grounded outlet before buying.
No. Wattage matters for speed, but turntable size, controls, sensor behavior, exterior dimensions, and how you reheat food day to day matter just as much.
