I'm pretty sure this topic has been debated to death on another thread, but might as well as add my 1.5 cents Canadian.
Coke will always beat Pepsi. In any poll, any taste test, any competition. Pepsi may have better ads sometimes, but over 2/3 of North America chooses Coke. I can't drink regular Coke anymore, it's too sweet. But the best cola I've ever had......ever.....is Cherry Coke Zero. That stuff is like crack!!! And we can't even get it in Canada. I can always tell when some waitress tries to bring me a Pepsi, it's like a watered down Coke. I usually switch to 7UP or Root beer. And Diet Pepsi is just water with bubbles...
