Reggie Bush Or Pierre Thomas?

Pierre Thomas has been tearing it up with the ground game the past few weeks with a handful of touchdowns, but Bush appears to be close to, if not 100 percent. Thomas is clearly the main running back, and has been in the end zone every week, but Bush is explosive in the ping game. Both put up good numbers last week against the Falcons. Last year Thomas put up over 100 yards rushing and 100 yards receiving against the Bears in week 17, with Bush inactive, its very hard to say which is the better play, the weather appears to favor the run, any thoughts?
