Coke because its the original, pepsi tastes way to sweet, and Pepsi's always doing something to coke in there commercials where-as coke just has fun commercials that never attack pepsi. I think weve all seen the lame jacky chan pepsi commercial. Anyway I also wonder if pepsi had that whole, "New generation" thing back when it was introduced because then you woud have these really pissed off old people saying, I though we were the new generation! Pepsi screwed us!
