Which brand of cola is more popular and why.?

Obviously Coca Cola.

Coca Cola has a longer history and they have better marketing ads. For example, a lot of the chain restaurants have COCA COLA rather than PEPSI. Moreover, Coca Cola sponsored the Olympics whereas Pepsi didn't.

Coca Cola

Coke hands down! Why? It taste better. Also, Pepsi is too sweet. I'd like to know what restaurants "JC" goes to all we have is Pepsi around here.

I think Pepsi is more popular because the advertisements are more aggressive and use more celebrities to promote their product. However, Pepsi has had it's flops...

Remember Crystal Pepsi? *Shudders*

Coke, Pepsi is too sweet. But Dr Pepper/Mr Pibb is my fave

Coke of course. Pepsi has a really sweet kind of flat flavor and coke has alot more fizz =]

I prefer Pepsi. I think Coke is too sweet. But my favorite soda is Root Beer no matter who makes it.
