I just performed a complete unscientific, non-blind taste test.
I like Diet Pepsi better.
But not tons better because I just mixed up the cups and I can’t remember which is which.
Neither Diet Coke nor Diet Pepsi are as good as milk with chocolate cake, however.
If you would like me to perform any other unscientific, non-blind and possibly even slightly rigged opinion tests, let me know.
