“American Express and Discover Card are very different in their fees, reward programs and incentives, and their strong performances indicate their ability to suit the various needs that dissimilar types of cardholders have,” said Rocky Clancy, executive director of financial services at J.D. Power and Associates.

“American Express appeals to customers looking for benefits and reward programs, and these customers are generally willing to pay higher fees for the additional value the card provides. Conversely, Discover Card has found success with customers looking for simplicity, which it offers through no annual fees, cash rewards and fewer problems than other issuers.”

Honorable Mentions: Chase, U.S. Bank, & WaMu

These companies received average or above average marks in each of the categories.
