The only thing the Decimate interesting free alternative to the slightly lower Voxel Size value.
Sorry I don't know I haven't used zBrush, I could never justify the cost of the tool when I get the same functionality out of something that is open source. Is ZBrush still so much better for character creation? But I think zbrush is easier for beginners in sculpting. I still do not see Zbrush being efficient in anything other than sculpting. In any case, I fouond blender easy to use to position shapes and run 3D like a sketch, and I can go jump in editmode and sculptmode use modifiers to build pieces, I use skin modifier very often when blocking out a character and in blender these operations are made very convenient and easy.
