1) The interface seems to be simpler, especially when making things a little bit more complex
2) Greater amount of CAD models already available in this format
3) Greater amount of resources and tutorials
And the Student version is only available to people with a valid current student ID, and saves files in a format that is intentionally incompatible with the normal version?
Nowadays I use OnShape because it's decent and the only thing that works on Linux. I do miss some of the more advanced features, though (e.g. simulation, or variables).

Skilled operators can likely work near-magic anyway, given sufficient time. ;)
Containers is a great next step from rings. They’ll encourage learning about fit, coordinate systems, and support structures.
So I suspect it is a SLAM system (how else can it make up an accurate mesh like that) but with a calibrated and well integrated depth sensor on there as well.
Photogrammetry will be your best bet. Also not cheap. https://www.autodesk.com/solutions/photogrammetry-software
I would really suggest learning Fusion 360 for mechanical or blender for organic modeling and build from scratch. It's a great toolset to know and can be very rewarding. It will teach your core skills that you can apply all the time with your 3d printer. If you have never done any 3d work before, start with tinkercad.com until you feel comfortable.
