Welcome there!
Do not worry yourself about the servers being full, there is a restriction on new character creation during certain times - peak of connected PC would be my guess, you only need to try and create your character as what seems like an unusual time and I can assure you, you will find yourself a comfy spot in the RP community. That said, I can only speak for Balmung, I am about 2 months old on the game, 1 with my character on Balmung, and so far it's been a blast!
I suspect you already read about the servers differences, but just in case, know that there is a thread that explains those thoroughly.
