What is the most succesful fighting styles in MMA, or at least which one has the moves that work the most?

Wrestling for the pure fact that it is a sport with rules. take downs are scored more than strikes, ground control is scored higher than striking pace control, and wrestlers are content with Lay 'n Pray. that's taking your opponent down and laying on them for the decision win and praying they don't get up or hurt you. it's why most of the champions are wrestlers. Frankie Edgar bored the world with his half-entertaining win over BJ Penn. and GSP has been cuddling his way through the welterweight division for quite some time now.
