Honestly, both WoW and TOR feel pretty similar. The only difference is, I'm excited to play TOR whereas I wouldn't even play WoW if it was F2P. WoW has over 10 years of development. Compare this to what, 5 years of story writing and 3 years of development. Not a fair comparison really, doesn't matter if the game has been online since 2004. MMORPGs are constantly evolving so 10 years of development will get a lot more done than 3 years of development. Even so I would never consider going back to WoW.
All I can say is give the devs more time. I think they've done a great job with the game. My only gripe is in some of the cinematics my IA shoots people with his invisible gun. My server doesn't have queue times so i consider myself lucky. But story is awesome (even the collect this kill that quests!) I like the no auto attack, I've found a group for every heroic, FP, w/e within 10 minutes of searching, the UI is weak, probably the worst feature of the game, but once mods are allowed (and don't kid yourself, they are coming) that wont even matter. The WoW UI was equally terrible from what I remember.
My advice is play whichever game you want. No one is forcing you, no one cares how good you are at games, no one cares how many commas I use, no one cares about your opinion (not review) nor mine.
