Obviously there is going to be a bias towards playing SW:TOR. To get a better idea as to what is the preferred "game of choice", you may want to post this question on a forum that is not apparently lenient towards either of these games.
Just my $.02
That being said, I stopped playing SW:TOR after a couple of months, and am currently returning. I went out and tried to play a number of games for two years, but something made me return. Perhaps it was the unique style of this game, combined with the uncanny artistic beauty of the worlds, the impeccable voice acting, and the lore associated with the game? Who knows? All I know is, I am back... and I plan on staying for a while.
In my time away, I tried giving WoW a number of attempts before finally giving up. There was just something about it that could not grip me; I even tried playing EVE, Guild Wars 2, and a number of others, but to no avail.
