This is my all time favorite server. The staff keeps up with everything, and during those annoying update times when bukkit takes forever to get back up and running. The staff keeps us satisfied with vanilla survival while we wait. I highly recommend that you at least give it a try. New members have all the same privileges as old members (except the staff members, of course).
The multiworld plugin is a great addition that allows for, like the name implies, multiple worlds. We hard survival, creative, Hardrcore (survival, but harder, with more rewards), Minigame worlds, pixel art world, and also frequent buildings challenges with prizes.
This server is an absolute ball! I hope see you playing soon.
