I sold my AW v1 and bought a Garmin Epic Gen 2. It was on sale, I figured, let's see what the fuss is about. Here is what I can tell you after about 6 months of using it.
First, I run about 60-80km a week currently, should get that up to 80-100 before my marathon.
What I like more about the Garmin:
1) Battery life. Ya, it's so much better. I went on vacation for a week, didn't need to bring a charging cable. Never have to worry about it. Never have to think about it.
2) Buttons. So much better. They are tactile, easy to reach..
3) Flashlight. I use it all the time. I use it in the middle of the night for a trip to the Lou.. I used to bring a flashlight with me when I went to the cottage, no need, the watch does fine.
What I like more about the AW:
1) I don't need to bring a phone ! Today, I went for a run, didn't bring my phone, my wife called me a bunch of times needing to know something, I wasn't answering, it required her to go home and change her plans for the day (long story).. she wasn't happy.
2) Apple Pay. I often buy things (milk, whatever) after a run. I can't do that anymore.
I'd say those are the main points. I will also say that all those fancy Garmin metrics are garbage. Training readiness and heat acclimation.. yada yada.. I don't trust them, they don't speak to me. They are fun to look at, but I'd never guide my training on them.
So really, it comes down to those above points.
I _think_ that when the AW3 comes out, I'll probably get it. I was going to upgrade my iPhone 12. I think Apple will EOL it at the end of 2026.. So I can get another two years out of it. Instead, I will get the AW3 and probably sell the Garmin. Not having to bring a phone with me, for me, out paces all the others..
