I am pretty happy with mine (Fossil Sport). Lasts about 2 days on a charge while the display is always on, has all the sensors and most important, I can run my own software on it.
This is pretty much true. Google doesn't seem to particularly care about Wear OS, Qualcomm can't make a decent chip for it, and manufactures aren't coming out with anything compelling. With wearables, it really does seem like it's mostly Apple Watch along with Fitbit, Garmin, and a few others.
