Where arew you based? I can tell you that both products are good, as for Map the following advantages it has above ESRI where ESRI also has advantages above Map. MAP 100% supports Shape files, you have the ability with map to properly communicate between your CAD/GIS environment. Although ESRI claims they can do so as well, there are some problems. Map then also has a drawing cleanup facility, which allows you to clean up inaccurate data, if you have nodes that needs to snap it automatically can fix it. Map avoids duplication, stale data and data loss. For more info on map contact me at email@example.com. It seems you might be is SA?
