A Fenix 5S+. A lucky garage sale find. I can't btw vouch for "fully debugged" on some of its fancier features. I mean map display? On such a tiny device? I'll just use my phone. But the basic sports stuff is rock solid.
Map display is incredibly useful for us outdoor people - having a map of a hiking track at hand is much nicer than having to pull out a phone constantly.
This holds true also for other sports - e.g. ski layer is nice to orient yourself on ski slopes.
(Also Garmin maps actually have sports tracks with better detail than software made for cars like GMaps.)
