I like Pepsi. it is not as harsh and the taste is slightly sweeter.
But it depends also on whether it comes from the fountain or not. fountain soda is soooo much better than the can. Now if it does come from the fountain I will take either coke or pepsi, I like both that way.
Coke from the fountain and only if it's formulated correctly. I actually make note of the restaurants locally that seem to have their fountain coke formulated correctly and then patronize those establishments. However if I'm drinking from the can then mountain dew all the way.
COKE!!! I hate Pepsi and it makes me so mad when I am at a restaurant or whatever and I ask for a Coke and they bring me Pepsi. I am a coke fiend, its my most favorite drink in the world!
