I always hated the unpredictability of watches that need charging multiple times a week. You never know when it’s going to need it and can’t get in a rhythm.
FWIW, my "rhythm" is simple:
- When I go to bed, I put my AW on its charger on my nightstand.
- When I get up in the morning I put my AW on my wrist.
- On days when I do a particularly long run or ride, I'll put my AW on its charger while I shower.
All in all though, the two are of different paradigms. AW is a smartwatch that has some training capabilities. Garmins are training devices with some smartwatch capabilities. Choose based on your focus. Maybe both and switch between them (which I did for a while).
As for Garmin Connect -- the iOS app RunGap will export AW workouts to Garmin Connect. Not quite as much detailed stuff (and none of the TE analysis stuff) as from a Garmin device, but it's still nice as a central location. I use AW for running and Garmin Edge 830 for cycling. I'm pretty casual about both though these days; I'm well into the "Grand Masters" age category and more focused on fun than growth.
