I like coke at McDonalds. They just have the recipe down pat, for ratio of syrup/Co2, I think they may even get a different recipe from coke. And I like Coke out of the tap some other places too, but I hate coke in the can or plastic bottle. Glass bottle is good too.
Out of the can, Pepsi is a lot better. Overall I think I enjoy pepsi more, because Wild Cherry is better then Cherry coke, and they have Pepsi Lime which is 10x better then Vanilla Coke.
