I really like that you can overlap multiple datasets to compare/contrast findings. Their territory building is pretty easy to use as well.

eSpatial is extremely easy to use when it comes to creating maps or territories. We utilize this to keep up with and modify the areas in which we service our customers.

It is easy to use. You can upload data sets, and then it maps. The formatting can be a bit redundant sometimes. It would be nice if when you uploaded information, it reverted to the last used settings.
