They all have so many different products its a tough call. I'll show you what I mean
Cola - Coke beats Pepsi
Diet Cola - Diet Pepsi beats Diet Coke
Other Cola - Coke Zero beats Pepsi One
Lemon/Lime Soda - Sprite beats 7-Up
Dr. Pepper has no competition by Coke so Pepsi Wins
Pepsi Max has no competition by Coke so Pepsi Wins
Sports Beverages - Gatorade beats Powerade
Cherry Cola - Cherry Coke beats Cherry Pepsi
Vanilla Flavor Cola - Vanilla Coke Wins (I don't think pepsi has a match)
Water - Aquafina beats Dasani
Lime Flavor Cola - Coke with Lime beats whatever pepsi has
Okay so I think Coke has 6 wins and Pepsi 5 wins. I'm probably missing lots of products/brands though
