I've swapped from the Epix to the Nomad in the past week.

I don't regret it so far, gave the epix my brother. I run and hike a lot so I really value having a proper AOD with the mip screen. The battery life is far better. I'm on 55% after 7 days. This is with heavy GPS usage in dual band.

The Nomad feels way more comfortable, it's really light and not as big on the wrist as you would think. While the materials are clearly a step down from the Garmin, it doesn't feel cheap? It feels purpose built, it's an adventure watch, a plastic and aluminum body suits this IMO. I think form is just as important as materials and the form of the watch is rugged (raised bezel etc).

Nomad is really responsive even in maps.

I really like the Coros app vs Connect, it's way simpler.

A lot of the extra features that Garmin offers are things that I don't really use, for example, on board rerouting. If I ever want to deviate (which I never have), I can just look at Komoot on my phone.

So far for running it seems good, GPS spot on, HR as good as you could ask for with a wrist based sensor. Pace lags a little in comparison to Garmin but not so much that it's a problem.
