I was on the Ultra for 18 months or so and came away from it feeling like a much less powerful and capable Garmin is much nicer as a daily watch. I found myself wanting to find reasons/excuses to justify the Ultra. Ultimately I couldn't, and it wasn't worth its cost, charging schedule, and lack of battery life.
I can see why others like them (they want WatchOS and Apple-specific capabilities). That stuff is useful, but not often enough for me to care.
Really, the watch was a regular reminder of how functional life was before the watch existed, if that makes sense. It's a genuine marvel, and yet... I got by (and get by) great without it.
