I think Nomad is much more like Blender than Zbrush. Blender is an amazing app for sculpting, and it is very innovative regarding the tools, like cloth brush, pattern masking, temporal IK, etc. For me the UI/UX is much better in general than Zbrush, I’ve always found very tedious to work navigating tiny menus in Zbrush but maybe some people love that interface.
Zbrush is just much more capable of handling huge amounts of geometry and has built over the years a very production friendly toolset, like mesh inserting, curves for arraying objects like zippers, scales, chainmail, or auto retopology, HD sculpting option, or just making a 30 million polygons sculptures a breeze to work with. Blender can’t do that but can do a lot , that’s another thing in common with Nomad, you can’t do 30 Million polys in neither app so maybe Zbrush is not the best direction to go, but I’m just a user, what do I know!
