Post#2 - Final update: Home Assistant Device Bridge is out and is a great addition to Hubitat for those hard to add devices. After testing a ConBee 2 for several weeks, I would call it the clear winner for joining Xiaomi devices and other non-Xiaomi, yet still difficult to work with Zigbee devices. No drops. Perfect response every time.
The Mijia Multimode Smart Gateway is still the cheapest option at a regular sale price of just $20 USD, but in testing the Home Assistant Device Bridge driver I discovered there are some HomeKit limitations I didn't want to live with. For example, although the Aqara Temperature, Humidity, Pressure sensors shows all its data in the Mijia app, when you join that to HomeKit Controller in Home Assistant, you only see Temp and Humidity because HomeKit doesn't currently support barometric pressure apparently. 
So for just $43 USD ($54 CAD) you can get the ConBee 2 faster from Amazon and you will be able to join all of the Xaiomi Zigbee devices that are available in North America and you won't be just limited to Xiaomi Zigbee devices. For example, I'm able to once again use my Lutron Connected Bulb Remotes as button controllers for the first time since leaving Wink 5 years ago! And unlike the Wink implementation, this is actually fast.
