I actually much prefer Garmin watches, due to battery life, the workout app which has no analogues on iOS, in terms of how it tracks reps and sets, the readable screen, etc. However, its the iOS with it was just unusable. It worked great on Android, but I am used to be able to reply to texts, and I couldn't to pretty much anything on the Garmin watch with iOS, except see some notifications. I hope things get more interoperable, but it's been like this for a decade, so it probably won't get better.
