I'm not an outdoor runner anymore, I have a home gym. But the only thing the Garmin did for me was measure my pace and distance. It wasn't any more or less accurate than my iPhone at the time (around 2010), it was more convenient.

If you train any sport with any kind of seriousness you usually end up needing more advanced training features, like HR pacing, zones training, intervals for speed workouts, cadence..

There is no way to do all that properly with an Apple Watch as of today. Not to mention the pain that is to wait for the screen to turn on to see if you are running at the proper pace/HR vs a Garmin watch.
