Not sure if troll or not

but... Legacy servers seems to have more population than non-legacy ones. You might find more end game people just because there's more people...

Just prepare for 90k and server overload at times.

I transferred from Mandragora to Balmung. Never really experienced any lag in Mandragora but on Balmung, my god... red dots (dc icon) everywhere when Odin pops, and sometimes a whole zone slows down because too many people are running fates grinding for their atma.
