I don't like to compare soft but I would like to improve 3dcoat with my novice experience. Navigation is good like traditionnal 3d software : very good point!!!!. All traditional modeling tools (retopo room) will be nice!!!!! The secret is to know if new user find his children rapidely or not????
At the first glance, it's not easy to know how to finish the model (sculpting -> transfert details -> paint room), to know the hidden surface mode toogle,.... For example, Zbrush has some hierarchy on his right panel side (ex : texture transfer = last section). Maybe, reorder room Tabs(Left to right : Voxel, retopo, paint, render). So to give a chance to 3dcoat, you need to see the good tutorials on 3dcoat official youtube channel. I have time so it's oK but for others????
I think all GUI's change should be trivial and centralized with the less hidden options as possible. So AbnRanger's Outliner can be a good starting point.
