Pepsi? You've got to be kidding, Pepsi would lose BIG TIME. I mean, Pepsi's main place with computers is spewed all over baffled2's keyboard when she's laughing. I say Spork and Coke would team up and totally kick butt.
Spork!! would win cause its a combination of a fork, which is pointy, and a spoon, which is used for bludgeoning. So you would have a pointy blugeoning object, the damage of which is only limited by the size and material of the Spork!!
