If you're already running Home Assistant, there's some benefit. I agree with you completely that it's a bear to try to maintain it as your primary automation hub and creating anything but the simplest of automations is very unpleasant on Home Assistant.
However, there's no denying they have a number of these really inexpensive devices working well with the Phoscon ComBee 2 Zigbee stick and I've read that the Zigbee2MQTT integration covers a number of the same devices too.
Just recently the community has added a very easy to use driver that supports automatic importing of HA devices that create entities (i.e. Contact sensors, motions sensors, temp/humidity sensors, etc.). This works really well to just have the HA box handle the pairing with inexpensive devices like Xiaomi Aqara and Mijia battery devices, Tuya, etc., but then do the automation on Hubitat, which is so much easier and very capable.
