I am an avid Coca Cola drinker. My mother has always been a Pepsi person. I don't like the bitter taste of Pepsi. Coke seems to have a better aftertaste that makes it more pleasant to drink. I've only used Pepsi to mix drinks or if that's the only thing available. In all however, Coca Cola is way better on the spectrum. Views Pepsi right out the water. It's so crisp and refreshing.
