I wonder how samsung's galaxy smart watch compares? I'd never own an apple watch because I'd never want an apple phone, but I might someday consider getting a smart watch. Seems the options are the galaxy watch or ...nothing?
For me it's been good enough to overcome "I could take it or leave it" - it's handy for reading alerts without pulling out the phone, and Google Assistant even works most of the time.
It's also nice to keep the phone on silent and just get a buzz on the wrist for calls and alarms. Plus smarthome integration if you do that.
Edit: Forgot Google bought Fitbit, but I still would bet Fitbit outlasts the Pixel Watch.
