Which hub works best across Alexa, Google and Apple HomeKit?

Multi-protocol hubs such as the Aeotec SmartThings Hub and Aqara M3 advertise compatibility across Alexa, Google Assistant and (for Aqara) Apple HomeKit. Budget Matter bridges like the Tapo H110 expose devices to Apple Home via Matter. No single hub is perfect across all three platforms, so reviewers suggest choosing based on the ecosystem you use most.
