(water clears but I still want to know)
to me pepsi max tastes super super sweet (to a point at which I don't like it), but it also tastes really artificial (I think they use aspartame).
But yeah I agree if I'm having takeout I prefer coke. (But sometimes I'd like regular pepsi, especially with spicy food for some reason)
I think in general all fizzy drinks are becoming sweeter and sweeter as the general taste palete changes (I like to call it tongue rot)
