Can't really ask a Georgian to choose between the two. This is Coca-Cola country. In fact all soda here is referred to as coke, even if are really asking for a pepsi, sprite, 7up, dr pepper. Waitress asks what are you drinking, you reply coke, she then asks what kind. Kind of humorous.
Psssst I like both, somedays I have a taste for a pepsi, and somedays I feel like a coke. But the majority of the time its coke.
