pop wars

It seems like it has been a reason for debate my entire life, what is better coke or pepsi. It rages on even today ad in our home there is the debate of what to buy when it comes to pop beverage. I am a coke drinker with my drink of choice being coke zero while my wife is a die hard diet pepsi drinker. We can compromise with me usually drinking diet pepsi bit what do you think, where do your loyalties lie?
