What is the advantage of this over Blender? Blender has been my go-to for modeling, sculpting, video editing, and so much more. I'm not trying to bash this, I'm just curious.
I've dabbled a bit with digital sculpting, and for me, Blender's sculpting tools feel really odd. I haven't tried out Dilay, but both ZBrush and 3D-Coat's sculpting tools are a more natural fit for me. Blender has a certain inaccuracy I can't articulate very well that makes it hard for me to use effectively
There hasn't really been any big changes in 3d modelling software for decades now (the video in the link shows tools available in blender, zbrush, sculptris etc). The only thing left to fight over is the user interface; the more streamlined the process, the quicker you can go from idea in your head to something resembling it on screen.
Most people swear on Blender because that's what they started with, others like 3ds Max,or Maya, or Mudbox, and so on. Again it all comes down to how efficient the tool makes the whole process.
Blender has the worlds most flexible UI system. If I could use it in personal projects, I would.
Blender also has options to set keybindings and layout to something more familiar for Maya or Max users. I'm sure it behaves like Vim bindings in most editors though, not really as useful as having full blown Vim.
