Really happy with my Fenix as well. It's only crashed once when recording where it lost data (3+ hour long GPS session), but other than that I haven't really had serious issues. I will force a reboot occasionally but the user experience is so much better than the Samsung watch I tried.

And battery life...I can put it in low power mode and it just works as a watch until I want to record an activity. And it has power for ~a month that way.
