If you use your watch for just athletic stuff and getting push notifications, Garmin watches like the Venu are a much better piece of hardware and software. The battery last for days, the app on the phone is better, the tracking is better, the sensor integration (Ant+) is better, and there are entire ecosystems that revolve around the Garmin/Strava combo.
IF you are looking for more of a SOAW (Smartphone On a Wrist), I think iWatch is probably the best thing on the market.
