I like mine but mainly use the health / activity features, such as the daily tracking of movement, calories burned, etc. I use it as my sport watch for running as well and it is comparable to Garmin now. I have disabled pretty much all notifications on it though.

Mine is a series 6 and have at least another year left on it. I may consider buying series 10 if Apple decides to do some substantial changes for the 10th anniversary release.
