I use Trimble and it works really well. I use the topo and aerial cached maps on my phone so no need for cell service. The land ownership overlay is great (it doesn't give contact info on landowners however, just color codes private vs NFS vs NPS vs BLM vs State lands) and is good for a number of western states for $20/year which includes some other features.
The ability to go over maps on your computer at home, create waypoints and tracks if you want and then send them to yours and your hunting partners emails to download to your phone is great. I think it creates gpx files so you could make the points work in other gps units as well though I've never tried. No topo/aerial overlay which is too bad but overall I'm a big fan of the trimble software. Battery life is great for me, I leave it in airplane mode in my pocket pretty much all day and only use it to aid with hiking in the dark and finding the tent at night, I can use it for days. I never owned a gps before so I don't consider this a replacement for gps but it is a handy tool for sure.
