I had a Fossil Q...something. It was the latest one and it had WearOS. It was okay, but I rarely ever used it. The notifications were wonky, and because the steel band never properly fit I would never feel the notifications, so I just relied on my phone anyway. I had a leather band put on it but the case was so huge compared to it I swapped it out again.
The screen was great, and the sound was nice, but it didn't feel like it was worth the price tag, especially since it didn't seem functional to me in the end. I had gotten it because I thought making and taking calls from it and receiving notifications would make me more productive, but it didn't. Half the time the notifications didn't show up, or would arrive a few minutes later, and people could never hear me when I answered from my watch (I never did figure out how to make outgoing calls from it).
My wife has an Apple Watch and she can't live without it. I tinkered with it and it's far more advanced in its synchronization with Apple phones than WearOS watches are with Android phones. Plus, while round faces are more traditional for watches, I feel like you need a square or rectangular face for smartwatches. Since most screens are that shape anyway, trying to make them round does not feel intuitive.
