I have a Starwood Amex which is the best card out there for miles earned for any airline, but I need a VC/MC for non-Amex shopping. I have researched MBNA Plus Rewards, Chase Travel Rewards, Fleet, and Orbitz Rewards and compared all the cards they offer. Minimal differences in terms of $ caps, geographic specificity, and annual fees.

Bottom line: Any one have experience with actually redeeming in these programs, and recommend one vs. another?
