I think it's mostly a simple matter of preference. To my eyes, this GM screen (my screen & map - I drew the white text/red lines):
Looks a lot more organised than this one:
I think even SmiteWorks - the people behind Fantasy Grounds - are aware that you totally could go out and get a free program if you wanted to, but I'd make the argument that most people would think the top image looks a bit less.....spreadsheet-y than the MapTool one does. SmiteWorks has made a few posts over on Steam even suggesting users try out the free stuff and see how you like it compared to Fantasy Grounds.
The part where Fantasy Grounds seems to have the advantage is all of their licensed material (would be awesome if FFG got in on that for Star Wars). They have a TON of licensed adventures and fully-automated tabletops for a bunch of different RPG series. In this case however, Edge of the Empire isn't one of them, it's simply a user-created ruleset much like what MapTool seems to have going.
I'm aware there is wiki stuff for the free programs, but nothing that ~I personally~ was able to find on my own regarding Edge of the Empire. Googling "MapTool Edge of the Empire tutorial" or the same search for Roll20 was always just giving me videos of people ~playing~ EotE sessions over the internet - not how to actually set the session up.
Daelkyr's work with EotE's MapTool ruleset seems rather impressive, but there is absolutely NO explanation whatsoever over on his forum thread for getting it running. Reading it, there's lots of "programmer speak"......I don't doubt that someone who is well-experienced with using MapTools or Roll20 in general could figure out how to run an EotE session with a bit of experimenting, but for someone like myself who is 100% new to this "Virtual Tabletop" stuff, MapTool and Roll20 scared me away because it was too confusing trying to figure out how to start something, and Fantasy Grounds had me up and running an actual game session ~perfectly~ from the time I downloaded it in the afternoon to the early evening when I invited a friend to join me.
(And all I can find for Roll20 just searching around is the mention of a dice script and ~nothing else~. If anyone actually knows of any tutorials specifically for Edge of the Empire on the free VTT programs, why are they not in big bright lights & posted at the top of this forum?)
