It did? I moved into a new home a year ago and have been outfitting it with smart devices. I have no real preference for Zigbee but ended up with a bunch of Zigbee devices and zero Z-Wave devices.

Z-Wave is somewhat better if you have a big house or many neighbours with 2.4 GHz Wi-Fi APs using the spectrum because it operates on the 868/908 MHz ISM band instead of the 2.4 GHz ISM band used by Zigbee and shared with Wi-Fi and BT devices. Lower frequency waves travel more easily through thick walls and further and the 868/908 band is also subject to airtime restrictions in order to prevent interference. ZigBee uses repeaters and more frequent updates to accomplish the same thing. Most wall plug powered ZigBee devices are also repeaters. You'll probably get more samples from battery powered ZigBee sensors than from devices either using Z-Wave (which has airtime limitations) or Wi-Fi (which is power hungry and the devices are in deep sleep most of the time).
