The short answer

Kasa Matter Smart Plug KP125M comes out ahead by a narrow margin (4.6 vs 4.3). The gap is mostly about smart-home builders who want one Matter plug that works across Alexa, Google, Apple, and SmartThings with energy tracking — read the strengths below before deciding.

Higher ratedRanked #1 in Best Smart Plugs

Kasa Matter Smart Plug KP125M

4.6

3 sourcesall derived$20.89as of Aug 1

The KP125M takes best-overall smart plug: TP-Link's first Matter-certified plug, with genuine energy monitoring and a slim profile that doesn't block adjacent outlets. Reviewed named it their Editor's Choice best-overall pick, and Engadget named it their Best Matter Plug. The trade-offs are minor: multipack-only availability and Wi-Fi rather than Thread connectivity.

Strengths

— Matter-certified, so it works natively with Apple Home, Alexa, Google Home, and SmartThings
— Built-in energy monitoring tracks real-time and historical wattage per device
— Compact slim body lets two plugs share a standard duplex outlet

Watch-outs

— Only sold in 2-packs and 4-packs, not as a single unit
— 2.4GHz Wi-Fi only, no Thread radio for mesh networking
— HomeKit connectivity can be spotty without an Apple home hub

Ranked #3 in Best Smart Plugs

Wemo Smart Plug with Thread

4.3

3 sources2 derived$27.99as of Aug 1

The Wemo Smart Plug with Thread suits Apple HomeKit homes building a Thread mesh: it pairs with an NFC tap and strengthens a low-latency Thread network. Engadget recommends it specifically for HomeKit users, and PCWorld confirms it as a HomeKit-only device. That limit is significant. It works with Apple Home and nothing else, so no Alexa, no Google.

Strengths

— Built for Thread from the ground up — fast, low-latency mesh networking
— Touchless NFC pairing: tap an iPhone to set it up in seconds
— Compact design that doesn't obstruct the adjacent outlet

Watch-outs

— Apple HomeKit only — no Alexa or Google Assistant support
— Cannot be controlled from the Wemo app, only Apple Home
— Higher price than Wi-Fi rivals with broader compatibility

How they stack up

Kasa Matter Smart Plug KP125M

The best all-rounder of the group. Unlike the Tapo P125M (now unavailable), it adds energy monitoring; unlike the Wyze Plug, it carries Matter certification for cross-ecosystem use; and unlike the Wemo Smart Plug with Thread, it isn't locked to Apple Home.

Wemo Smart Plug with Thread

The only Thread-native and HomeKit-focused plug here. Where the Amazon Smart Plug is Alexa-only and the Wyze Plug is Alexa/Google, this is Apple-only — but it's the one plug that extends a Thread mesh, something neither the Wi-Fi-bound Kasa Matter Smart Plug KP125M nor the Tapo P125M (now unavailable) can do.
