I understand and agree with some of that. But, comparing OS by software availability doesn't make sense.

Credits and discredits should go not to Linux community or Apple and neither to Microsoft. If we do not have Adobe stuff for Linux, it's Adobe's fault (some would call it 'strategy').

People often turns that "OS battle" into a "third party vendors battle". Probably, Adobe do not see Linux as a strategic alternative or maybe they're just being blind themselves.

If you do want to compare Linux/MacOS/Windows/WhateverOS you must focus. Try comparing MacOS against Windows with the same tools and you'll have a result of the OS itself and what it does provide to the application you're running (and do not forget what is under the beautiful face of MacOS).

Anyway, you're absolutely right regarding just leaving 3dmax behind. I'm not skilled to tell about 3DMax vs Blender, but I'd try learning it, not as a substitute but as another skill.

My best wishes!!
