I actually did do garmin watch for 5 or 6 years before recently jumping to apple. In most ways I did like my garmin better.

My only day to day upgrade with apple watch, is it allowed me to stream music to my airpods on a run without my phone. But I think Garmin has since released phones that can store music..

I'm not using my apple watch to run "apps" past podcast/music/running tracking.
