I'm sure every server has it's good points and it's bad points, and a lot of the good points and bad points are the people who play on them. If you're trying to find the best server for you, I suggest either seeing if any of your offline friends play, and which server(s) they play on..or making a newbie character on each of several servers, and just hanging out for a few days in heavily populated areas and seeing what the general personality is like.
Of course, if you're looking for a server that is more or less populated, or has a greater or lesser percentage of newbies, or a greater/lesser percentage of "uber" players, then you'd have to look up stats and stuff. Stromm is probably a good server to go to if you're looking for less twinkage and more new characers, for example.
Hope the info helps =)
