MilesBuzz! - MasterCard: currently most ff/best to get?

I went through search and Pgary's Free Frequentflyer Miles and could not decide which Mastercard gives the most ff or points for the least cost of annual fees or no annual fee, or which wave their annual fees. Suggestions would be appreciated.

Full information on this subject can be found on the credit card pages of my website, Free Frequent Flyer Miles (http://www.freefrequentflyermiles.com/index.htm).
