I also have a Fenix 3, after having to Suunto watches previously. I like Garmin much better than Suunto.
In the mountains, I usually have activated both my Fenix 3 and my smartphone GPS topo app, both which record gps trail. I find them both equal.
I think the variation in tracking accuracy you mentioned is probably normal and should be expected with all such devices. Frankly, I consider their accuracy (10m to 30m) is actually adequate.
