Why not just try out both and see what's a better fit for you?
Personally, I'm a new RPer to the scene, but I've already managed to make a lot of connections to veterans and other new players alike. Also there was a poll held recently where people were asked to vote which server they were "choosing", that thread was eventually locked as well, but it did give us some interesting information.

The poll results show that of the people that voted on this website, 81 are going to Balmung, and only 14 are going to Gilgamesh. If your goal is to shoot for as healthy an RP community as you can manage to include yourself in, with as many opportunities to build connections with other RPers that you can manage? Then Balmung is the smart choice.
