Like Extremo said, all are good choices.
(only speaking from what I know about 2013)
Contact pros are hella light have a lot of lateral flex (which I like). They also seem to work just as well on a really soft board as a stiffer one.
Forces are more responsive and have a taller highback, they're plenty comfortable and you get a LOT of response out of them if you crank the forward lean.
Atlas is somewhere in the middle....probably my favorite binding. Super comfortable and soft and mellow when you need them to be, and responsive when you need them to be.
