I have also voted with my money for IKEA Trådfri and am quite happy with it. Light bulbs, motion sensors, remote controls. Everything connected to zigbee coordinator and controlled with simple node red flows. And good thing is that list of supported devices is longer than any other single vendor with option to expand it by your self.

Baby starts moving in bedroom, light bulb flashes in kitchen.

Sonos stopped supporting remote control, no problem, map IKEA remote controller to start/stop Sonos playback.
