Nomad Sculpt vs Zbrush for iPad

A bunch of people have been messaging me on Instagram asking what my personal preference is between the two. I have been using Nomad sculpt for the past 1.5 years and recently started using Zbrush for iPad as well. FYI: sculpting on my iPad for me is a way to relax, be creative and experiment, in contrast to my day to day work that have to be game ready assets usually strictly following a concept.
