Well Thread allows devices to require internet connectivity to pair. It also allows devices to fetch firmware updates from the manufacturer. And it allows features to be locked to their specific app. Thread and Matter are more complex to setup self-hosted style; it makes no difference when you use official hubs though. Thread doesn’t have many device types and manufacturers available.
Zigbee does not require or work over the internet, no trust required. It is very easy to setup self-hosted. There is a Zigbee everything made by everyone from large companies to random brandless places.
Zigbee is my preference as a result of the internet connectivity requirement. I do not trust random manufacturers to not brick my devices when they go out of business or choose to release a competing product.





I love to hear about a Canadian alternative.
