I've played EQ since 2003 and box 3-4 accounts on a regular basis. I tried to play WoW a couple of times because some friends had switched over and I ended up getting really bored really fast. It was nice to see my xp fly so quickly, however I felt like I didn't have to do much work to get it.

IMO it kinda comes down to do you like to quest/tradeskill etc more or do you enjoy the grouping/grinding xp more. Graphics and such do not mean as much to me as game play and server reliability.
