While the idea of realistic (read: skeuomorphic) faces has interested me, the functional shortcomings of Android Wear as well as my more recent Galaxy Watches didn't make up for the trade-off. My Active didn't accurately track sleep-If i went to bed and woke up two hours later to use the bathroom, and went back to bed and slept 7 more hours, my watch would show TWO sleep records, one for two and one for seven. That alone would mess up any chances of tracking it accurately and counted against any achievements in Samsung Health. (they do have achievements similar to AW)
Also the heart rate sensors in the Galaxy and Wear OS devices aren't the best at all. hardly even remotely good. Steps are counted wrong, exercise data is off by a mile or two, etc. Then there's the unfixed bugs I've had regarding Samsung Pay (Stay connected to phone error even with my phone next to me connected, forcing a remove and re-add of my card every five purchases) as well as Bluetooth (had to manually reconnect both my Gear S3 Classic and Watch Active to my S8 often even though my phone was near me the whole time--watch kept showing 'standalone' in the status--remote connection was completely broken. Gave it three generations of watches to fix, the S2, Gear S3, and Galaxy Watch Active. It's still bugged. Tried other phones too. No fix.
