Looking at both teams, and hopefully without prejudice, and since I don't much care which team wins, I think Seattle will win it by less than a TD.
I'd like to see Seattle win it, not because I like them more than the Steelers, but Pittsburgh has been there and won it before.
I wont really be pulling for either team, and no matter which team makes a great play, I'll applaud them for it. In all likelihood though, I'll be rooting for whoever has the ball... I love offense, what can I say...
