I haven't played either of the Star Wars MMO's, but they look worse than the ones I've actually tried, so not even going to go that route.
The MMO I still play to this day (though on an open server) is Ultima Online. It was just the right balance of skills, pvp, and world. The funniest part of the game was when people would find a way to use a crap skill in PvP that gave them a huge edge all of the sudden, then everyone switched over to new character builds to take advantage of the Camping or Music skill. Too bad that's another franchise EA Purchased and killed.
