Which smart plug works best with Alexa, Google Home, and Apple HomeKit?

For the widest cross-platform support, reviewers point to Matter-compatible plugs such as the Tapo P125M and Linkind Matter plug, which advertise Apple Home, Alexa, Google Home, and SmartThings support. The Amazon Smart Plug is the narrowest—community threads note it is optimized for Alexa only. Kasa Wi-Fi plugs work with Alexa and Google Home but most non-Matter models do not support Apple Home.
