Mapwel versus GPSMapEdit and cGpsMapper?

Questions:
1) What is lost when importing an MP file?
2) What map/GPS features can MapWel implement that GPSMapEdit and cGpsMapper cannot?

I have a lot of time invested in building a local map with GPSMapEdit. The limitations I ran into first are the limited POI categories and Search Intersections - compared with other professional map products for Garmin.

I just installed the Garmin tool to play with. I'm sure it can do everything. 2 problems. First is the conversion from MP looks tedious. Second is if I ever want to do something legitimate with it - the cost is a show stopper.

MapWel advanced is affordable - IF it is worth conversion.
