One reason that I stay in STO and play it more often than TOR is the players. TOR has all sorts of random players, but they're all isolated in their own little gaming experience. STO already has a community in its game. Star Trek no matter what, is always a strong community willing to work together. It's that together bit that really exemplifies the real MMO experience. I may just be blathering because I can't find a group in TOR for anything or it might be because I'm in a fleet, but I find STO a better game for the most part because of its players.
