In the spirit of World Cup competition, we're holding our own tournament in search of the Better Stock Today. We're pitting 32 companies against each other and you, the reader, will determine the winner.

Facebook takes on American Express for this first round-robin match up in our search for the better stock today.

Motley Fool tech analyst, Jamal Carnett, thinks Facebook (NASDAQ:FB) should advance to the next round because of one big reason, the price still doesn't match its potential. Right now, Facebook is the first webpage many people visit in the morning and that's immensely valuable to Facebook's real customers -- marketers. In addition, Facebook is looking at growing both users and viewing times. Facebook has redefined the Internet, and will continue to grow its massive ad-based revenue at a healthy clip. That's why Facebook deserves to win this match.

Financials analyst Tyler Riggs believes that the number one reason American Express (NYSE:AXP) is the strongest buy in the field is the company's extremely strong competitive position and -- most importantly -- what this means for the future of credit cards and payments. In terms of strength, American Express is unmatched in the credit card industry with its focus on just a key segment of cardholders: those who are more affluent, which means less risk and more spending. In addition, the company's unique closed loop system puts it in an incredible position to capitalize on the changing payments landscape.
