Well where I live all soft drinks are referred to as a "coke", whether it's Coke, Pepsi, etc. but even with that in mind I've generally preferred the taste of Coke to Pepsi. I don't drink a lot of soda anymore but Pepsi has a lot of different drink products out there I think and so does Coke, including things like bottled water. So it's something to keep in mind not just for soda/cokes but also for other types of drinks.
