A lot of the folks here are Balmungolians, including myself, so I can only give you what general information I know about both. Information that is slightly skewed more towards one than the other, of course. So I'll start with that one.
Balmung has a decidedly larger RPer "pool", as it were. A lot more people wandering about and doing RP. This includes FCs and LSes that are for RP purposes, as well as generic walk-up RPs in places like the Quicksand in Ul'dah (you can usually find at least a couple folks milling around there looking for RP at most times of day). It also totes folks from a wide range of locales, so hopefully you can find someone or someones that fits your time schedule.
Gilgamesh, from what I've heard, has a smaller RPing community but also a more close-knit one? They also have their own boards separate from this one at... gilgamesh-rp.com, I believe. Hopefully one of the Gregs will swing by and be able to give you more information about how RP is like over there.
Of course, with Forum RP, you can hang out with folks no matter what server they're on!
