> What I’m asking is how do the output and performance differ. From a non-technical perspective I was able to do (reasonably?) complex part design with almost no prior experience in about 3 days of work. This included debugging the model code, introducing various enhancements after realizing I would need them, completely changing the design a couple times after running real-world measurements. In blender, based upon past experience, I would have spent a week just figuring out how to do all that. Sure there is code and the like, but how easy is it to hook that up to your external editor? How well does the refresh cycle work? (Hint - in OpenSCAD it just worked and I could use my editor of choice on a second screen monitor). So the non-technical performance is pretty great. The technical "how fast does it go" - I'm not sure but I suspect Blender uses GMP under the hood as well, at that point it is somewhat arbitrary. I dont think the tooling is geared towards doing model designs, I get the impression FreeCAD is more the SolidWorks contender - which is next on my list to evaluate. Thanks for the tip about geometry nodes though!
