I like coke better but either will do. When it comes to buying, it's whatever's cheaper. Funny this thread came up, about a week ago I went to a friends apartment knowing she didn't have soda. So, like the nice guy I am I bought a couple 12 packs of pepsi(was on sale). As soon as I walk in the door she starts yelling, "I only drink coke! What a waste!" Last time I try to do something nice for her! I had no idea some people live and die by either coke or pepsi, lol. If it's caffeinated brown s***, I'm drinkin it!
