What is the most populated server?

[ChameleonMS]

The biggest advantage of changing from a low population server to a high (switched from Goblin to Gilgamesh 16 months ago) is the PFs will fill faster.
A normal prime time PF list:
on Goblin has 5-7 PFs
on Gilgamesh has 25-35 PFs

As other have stated, the Duty finder for the Aether data centre performance will be the same but you will have a much easier time finding others to run stuff directly from the server population.

The MB prices on Balmung seem way way cheaper than Sargatanas[and Sarg probably less than smaller servers as well], also due to the population of many players, but that shouldnt be the only reason,
There are definately more pf entries up at any given time as well, things to consider before moving, and leaving your friends(or take them with
you)

I dont think ive ever been accosted by RP'rs they generally put status messages in their char info like "walk ups/tells welcome" but say chat is usually flooded in some areas(ul'dah)
