Green or Blue?

[Jabober]

Sup guys! I'm returning to the game, but won't have near as much time to play. I grinded my Druid Kimchisoup to 60 in about 30 days played a couple of years ago I believe and want to do something similar with a Bard. I plan on swarm kiting with a mix of grouping when I'm bored. I also want to potently raid a little on my Druid or Bard. Do you guys prefer Blue, or Green server? How's the trading market on each server? Overall, which do you feel is more fun?
