Blows them away? I haven't seen anything that is not just one or two features that other watches don't have. But all the.features require the watch to be on.
Data accuracy most certainly is not in relation to GPS which often cuts distances on the Apple Watch.
People like to complain about the GPS but I use it when running and it'll easily show me what side of the path I was on at any given point. And the path distance matches precisely with other sources of truth. Maybe there was a time when Garmin had an advantage on some of their watches but I am far from convinced that this has been true anytime in the past few years.
