As a hobbyist I can't imagine using anything but OpenSCAD. I know it's not comparable in capabilities and has its quirks, but it feels like Python for CAD - I get stuff done quick. It's so simple the cheatsheet covering 100% of commands takes up one page, so I don't need to waste time looking up details. And as it's all code it spares me from clicking through all kinds of menus.
I do miss FreeCAD's chamfer & fillet tools, though.
Where FreeCAD ought to be able to take over is in the things that are a bit more complex that OpenSCAD just doesn't have the tooling for. Multiple-part assemblies is one of them that immediately comes to mind, now that there's some reasonable FreeCAD functionality for it.
