Trimble apps are quite nice. A bit convulted in interface, and I like Gaia better, but their online trip planning thing is superior. Quite decent for a phone-based solution, and they have versions that are especially nice for hunters. I think the cool features still require a subscription.
Been using the Oregon; very nice that I can use custom maps. They overlay in the handheld quite well. I use QGIS to create georeferenced maps from say scanned paper ones. Very cool. Garmin's US Topo 24K maps are meh for trails. Pretty decent for USFS roads in CA.
The Basecamp software on the Mac stinks. Crashes a lot, and several features are broken right now (like the trip planner). I can't believe they do such a poor job with it. Fortunately, the GPS unit itself is super easy to use. And it shows up as just a USB mass storage device. So cool after years of struggling with serial connections and wonky USB/serial adapters. Yippee.
