And my guess is that your "operate as the should" is probably some very personal opinions about how an OS should function based on your personal workflow, that you assume should be the defacto standard.

But for the sake of the argument, lets just assume that your standard is actually optimal from an efficiency standpoint. In that case, the argument to make in case of Mac would be this: Out of the box, Macs are closer to optimal, but technically Linux is is better because you can customize it to be exactly optimal.
