POP god damn it
By a decent margin.
Mostly because the dumb hicks say "coke" for any flavor of soft drink and then try to justify it with the "Kleenex" and "Q-Tip" defenses, which is like comparing apples to oranges. If I ask you to hand me a Kleenex, and I get any brand of tissue, I got what I wanted. If I ask for a cola flavored soft drink AKA a "Coke" and you give me something other than Coke, Pepsi, RC, Dr Pepper or any type of cola you've ****ed up big time.
