PepsiCo has emerged ahead of Coca-Cola Co. in the US cola stakes, according to the University of Michigan's annual consumer satisfaction index.

The index showed people liked Pepsi products better than they did last year, while Coca-Cola has moved in the opposite direction.
Satisfaction fell two points among Coke drinkers over the last year to 82 points on a 100-point scale, while Pepsi and Cadbury Schweppes shared the highest index rating with 86.

Coke spokesperson Scott Williamson told just-drinks: "People in the US vote for their favourite soft drinks when they buy them every day, and we lead in the top three categories with Coke, Diet Coke and Fanta."
