Over the last 12 years I have used MS Streets and Trips, Delorme Street Atlas, Mapsource (Basecamp predecessor), and Basecamp. When Basecamp came out I too fought with it as it doesn't work like the other mapping programs. But having map updates a few times a year made me figure it out. Now I have libraries of Campgrounds and POI's that I can pick from as needed. I can do anything in Basecamp that I did in any of the other programs.
One of the really nice features in Basecamp is the interaction with Google Earth. With three keystrokes I can toggle from an object in Basecamp and show it in Google Earth. Great tool for verifying locations and routes.
Basecamp is a great tool (if you are the owner of a Garmin GPS with Lifetime maps) but the learning curve is high. Like all mapping programs Basecamp has operations I do not like so I have to work around them. Once you master it you will not go back.
P.S. Save time and frustration, don't mess with the Trip Planner.
