Coca-Cola and Pepsi are both the most famous drinks in the world with many preferring Coca-Cola and many preferring Pepsi. 

I myself used to prefer Coca-Cola up until Pepsi Max was released and after trying Pepsi Max I could no longer drink Coca-Cola and enjoy it. Even with the Coca-Cola Zero that they have now, I still can not drink that over Pepsi Max now.

Which do you prefer Coca-Cola or Pepsi?
