Sodas contain fizzy water, sweetener, and an acid (among other stuff). The first two sodas you mention are flavored with phosphoric acid, and the second two are flavored with citric acid. I don’t know for sure if this is the active difference, but if you look at the ingredients lists of coke vs. sprite, it’s the main thing that differs between them.
