Can you taste the difference?

I think cola is. Pepsi tastes slightly watered down

When it comes down to plain cola pepsi is better. But when you get to flavored cola (eg cherry coke, or vanilla coke) coke is definitely better

adrianpeterson is right Pepsi is sweeter and coca-cola has more of a sharp, biting kind of flavour to it. That's the best way I can describe it.
And this is from someone who actually likes coke better.

Not in canada. Libtards are red
