I'm in the market for a fitness smartwatch focused on running, I have a Garmin 500 something for my bike - it was a gift - and I totally hate its UI/UX. It's not touch, super slow to refresh, maps already don't get updates, the Garmin "generate a random track" sent me on gravel/rock terrain when I have a road bike, the app try to cross-sell you other shit etc. Is at least the watches UI better?

I was now thinking to purchase a Coros Pace 3.

Try a Suunto. Very different than Garmin. (I found better battery, and menu.)
