Map Buddy seems to be a more user friendly experience.
I find it easier to create routes using waypoints as the map allows you to scroll around while you have selected the waypoint tool. The turn by turn directions are in a much better format and easier to follow. I have found it easier to create routes to a site as when you drop a waypoint it gives it a number by default as opposed to Mapsource which gave a physical address.
The maps themselves are much more detailed and have more road names on them as opposed to just PDR #’s. In general I find MapBuddy to be a little faster to do a lot of the things that I used to do using Mapsource.
We have been using Patchmap for numerous years now and we could not survive without it.
