i prefer dr. pepper over coke sometimes because it feels a lot smoother in my mouth as opposed to how sharp coke can taste. coke can be very refreshing if i'm thirsty though, but when it comes to coke flavors, i prefer cherry coke.
i don't really drink pepsi much- the last time i had a bottle of that was when they were doing a limited edition thing where they used real sugar. that was pretty good, but despite that, pepsi still sits at the bottom of my list.
