I agree that it's too early in their careers to tell - mainly in the case of Munoz who is only now seeming to utilize his wrestling in MMA. I thought that actually gave him the edge against Leben because he was able to out-slick him and maneuver to Leben's back on more than one occasion. But that said - Chael has been nothing short of monstrous over the past two years or so. Choosing between the two now - one has to go with Sonnen based on more higher profile victories - but he is plagued by his losses as well. Munoz is still developing so in the long run he could turn out to be more effective. Only time will tell.
