It's one or the other. Not both. Never both.

they're not, Pepsi is sweeter, whereas Coke is more acidic, i personally prefer Coca-Cola

Coca-cola is my addiction.

Well, one tastes like the sweat of peasants were dribbled down the crack of stephii's hate(and other stuff)-filled dumper, and the other tastes like coke.

Its like when people compare Sierra Mist to Sprite. -.-
