I like to throw around the phrase "Pepsi Challenge" as a way of indicating something is a worthy competitor. However, I have realized that Coke is always the sure winner in the Pepsi challenge:
Coke C2 <comic book guy>Best... Drink... Ever</cbg> It is the perfect balance between the regular "high-octane" Coke (which has too much sugar IMO), and Diet Coke which should only be used to strip paint off of junkyard body panels as a science expriment. Pepsi, quick on the heels of Coke came out with "Edge." While I do feel that Pepsi has the 'edge' (pun intended) on Coke in the diet drink category (more on this below), "Edge" simply tastes like someone poured 50% Pepsi and 50% Diet Pepsi into a bottle and relabeled it as "Edge."
