I don't think there is a single program that comes as complete as Poser is packaged. Every other program requires rigging skeletons, setting hierarchies, grouping polygons, and assigning textures. Poser has taken out that much labor for the figures available. And with online communities and brokers, that's alot of figures available. There are some specialty programs, such as RenderMan, but that requires tweeking. Poser is way cheaper!
