I still recommend RealThunder's fork (https://github.com/realthunder/FreeCAD/ https://github.com/realthunder/FreeCAD/) at the moment, even though his fork is a bit lagging at the moment. Most of his contributions to the topology fixes got merged back into freecad now, but his enhancements to UI/behavior aren't (yet), and they make a night and day compared to ondsel too. I didn't find any significant limitation to RealThunder's assembly3. In any case, while far from most commercial offerings, FreeCAD is progressing and the future looks bright. I've stopped using f360/onshape in the last years for my hobby designs. Once you know the specific limitations of freecad+occt (something you learn in each cad program) and how to work them around effectively, it's already pretty powerful.
