Lol. While I appreciate the insight, “lack of familiarity” is the “skill issue” of open source projects. I’ve got plenty of experience with both, and I’ve regularly used blender for well over a decade now (which is why I dislike it so very much).

Toby models are fun and speed modeling is a useful way to train, but performance in speed modeling does not equate to usefulness as a design tool. We used to do speed modeling challenges in scad, and while a diverting way to build skills, it has absolutely no bearing on that suite’s usefulness when considering things like: complex assemblies, top-down/bottom-up design, rapid iteration, iterative design tools, surface modeling, parametric design… etc.

I know many people who speedmodel in Rhino, and while I respect the hell out of the masochism their skill, it will never be my first choice for designing a functional part when I have other solidbody modeling tools to choose from. Similarly, I’d never use Alibre or Fusion for cosmetics or complex surface modeling of a part. They’re just not the right tool for the job.
