I've also dove into all of those, and have mostly stuck to OpenSCAD now. I'm not amazing at it, but I've been able to get a few things done that I needed for 3D printing. What has really made much better at OpenSCAD is ClaudeCode or Antigravity in VSCode, with BSOL2 library. The documentation is just bad enough that it takes me forever to figure out on my own, but just good enough with lots of examples out there that an LLM can get mostly what I want with little fuss.
