There's at least a few interesting points for zigbee: * If you use universal hub like Home Assistant, they are pretty interoperable between various manufacturers * Devices don't have direct connection to internet (again esp. with HA), so better privacy, they are faster (no cloud lag) and do not depend on internet connection * Battery life is way better for small devices * Mesh is nice when you have bigger area to cover * If you have to use shitty ISP router, it will have issues with large number of devices * Usually easy push-to-pair setup And there isn't many downsides - one time cost of some kind of coordinator and very slightly pricier equipment.
