This has been a favorite question of soda lovers since I've been coherent enough to understand it, whats better coke or pepsi? Its a unique question for each person, but I like to do this kinda thing, so I'm going to describe how each is for me while you think about it and ask yourself how close it is to your description. By the way, the thing that inspired me to do my thINK on this is the song “We Didn't Start the Fire” By Billy Joel, which at the end says “Rock n Roller Cola Wars...”
Lets start with coke, which more people seem to like. It never ceases to amaze me how different a carbonated beverage taste based on its container. My personal favorite is coke from the fountain or glass bottle. When I take a drink of ice cold Coke-a-Cola from a can it has a burning sensation in my mouth and down my throat. The taste of Coke-a-Cola is unique in and of itself, the burning sensation being part of that. Coke-a-Cola from a fountain or bottle has that same taste but not as much of the burning sensation, which I think makes it taste better and more refreshing.
Pepsi, however, doesn’t have the burning sensation of Coke-a-Cola. Although it doesn't have the burn, it does lose most of its drink ability when it is lukewarm and/or flat. It is very refreshing while iced and it has an almost vanilla like taste, which is brought out with the discontinued Pepsi Vanilla variant. Pepsi also has a substance in it that after drinking some it leaves a chalky texture in my mouth. Coke does the same but not to the same degree.
Its really your preference which one you drink, if any at all, but I just wanted to put my two cents out there for everyone to see. For the record, I'm a Mountain Dew fan. I like the citrus and fruity drinks. I find them more refreshing. I don't think there is an answer to the question of whats the best soda, but that won't stop the Rock n Roller Cola War.
