For both "Clay" type sculpting and 3D texturing I would think this is better value and potential than Z=Brush. The beta of version3 is just amazing. Painting on 3D feathers would be quite simple.

Even so, for very quick ideas--and I know not related to the end results required,---I was quite pleased at how quickly I was able to do this in MoI/Carrara this morning.
