What are the best credit cards to have if you plan on traveling/living abroad?

I am wondering which credit cards are best for those planning on traveling abroad often for business. If I am going to spend most of my time outside of the U.S., what kind of credit card should I get? Should I aim for one with no foreign transaction fee even if it is more expensive and/or has fewer benefits?
