Hi! I got the game not long ago myself, I think you'll enjoy it. That said, Balmung and Gilgamesh are both good choices! Gilgamesh is my main, and I have def seen RP going on as I've moved through certain areas. I started out in Limsa Lominsa, I caught scenes in progress quite a few times there. I'm still a baby so I'm just now branching out.
Gilgamesh is quieter as far as events and number of linkshells go, but I've never had to wait in a queue to log on as I have with my Balmung alt. You may not even have to worry about that though, depending on when you're trying to log in.
