Zbrush is supposed to be the daddy of these type apps and this sculptris was emulating that but had this neat automatic face subdivision which I thought was cool at the time. That might have the been the reason. I found sculptris easy to use but its like a set of pens or paint, its only as good as the sculptor but then at least your not fighting with the software. Blender has this built in too and thats pretty easy to use as well. Spoilt for choice now.
