I don’t use SU, and it having loads of display options does not impress me. I find Rhino options interface perfectly fine (and not arcane). Having decent control over how things are displayed, and setting them my way is much more preferable to mass user generated modes that SU might have.
Rhino 5 by default includes fixed number of display modes. And there are additional variations (of the default modes) you can find on wiki or create your own. Creating your own is very easy, use the variations from wiki to understand how the settings can be exploited. From what i understand, there are 6 distinct display modes in Rhino: wireframe, shaded, rendered, ghosted, x-ray, and Technical. Pen and Artistic modes are variations of Technical display mode.
