Hi Lane,
I have a bias that maybe you share, but hiking infers:
1) your out of cell tower range
2) want long battery life and easy to swap batteries (AA)
3) want GLONASS, or as many satellites to fix anywhere
4) rugged as hell
5) No real need to have the navigation device on all the time. You want to go somewhere, drop a waypoint, nav to it. turn off, and when needed, turn back on to fix your nav to the position.
6) Floats?
7) Barometer, electronic compass.
8) Buttons. I'm in cold areas. gloves with touch screens don't cut it. Muscle memory, hitting the button in the same location is incredibly powerful (find Goto) and hit enter button. Try that on a touch screen.
In my opinion, this puts you solidly in the PND (personal navigation device) arena like the Garmin. Garmin is still world leader in this, and a huge support network.
Maps for free come with their own issue, so the 99$ or so TOPOS from Garmin are a huge cost savings (time to find a map, download it, connect to device, yadayada.
A Garmin with map space to hold the entire US on a 4GIG disk is possible. A topo is certified correct by USGS. They have issues too, no doubt, but contours, peak heights, etc all baked into the TOPO is undeniably the easiest.
New Garmins have the Imagery subscription for 20$ per year, but really, is staring at an image taken from space get you anywhere?
Go Garmin. My favorite is the 76CSx (floats, discontinued, but incredible). Modern equivalent - 64.
