According to these claims, Pepsi was served chilled, while Coca-Cola was served at room temperature, thus making the Pepsi more appealing.
So that anecdote is bullshit. Everyone with refined tastebuds knows that Pepsi taste like sweetened dishwasher liquid and Coke is much more spiced and refined with notes of bitter vanilla, nutmeg, and pepper. Pepsi is what people who eat Doritos and Mountain Dew prefer, ie. they don't care what they consume.
If you are already eating junk, soda is not appreciated, it's consumed rapidly. All soda is going to be similar in that vain. The point of coke is that you can put a glass on ice, and drink it very slowly for the flavor. Drinking soda in any other capacity doesn't make much sense, and is poor decision healthwise.
