I think some people might have a misconception that Pepsi does better due to the very popular Pepsi Challenge marketing campaign. But if you think about it, that campaign is a classic "underdog" campaign. It would be silly for a product that's already winning in the number one position to "challenge" the number two product.
The "Pepsi Challenge" was the brainchild of none other than erstwhile PepsiCo president John Sculley, who you mind remember for later running Apple into the ground.
