I like that this program allows me create my own map from scratch or use one with an assigned style already created for you by another user so it's easy peasy! The process can be made more clear as there are some things which could stand improvement (I didn't find how do add new countries in particular; also when exporting files sometimes they get corrupted).
This should work well if your just need simple mapping without too much customization on each layer but maybe I am missing something here? Also have had little experience doing customizations myself since we hired someone else before who really knows his stuff about GIS tools/programs - he did wonders at our place though :) We needed quick solutions after having issues regarding land registry information while developing housing projects back then and was able solve those problems pretty quickly once i figured out where exactly what went wrong through trial & error method.
