I have a Unifi home network with two Wifi 7 access points and gigabit ethernet. For home automation, I went with ZWave and do not regret it at all. It's been rock solid and I've never felt the need to get a dongle to debug the traffic. I don't want to be working through all of the WiFi baggage with my home automation devices. I recently introduced some Zigbee bulbs (hue and cheapos from Amazon) and they've been mostly "fine", albeit with lower range.
