Most of it is there but you need a crap-load of third party extension and some even cost money.

Like proper alt-tab, better keyboard configuration, Finder is the worst file manager I have ever used, a classical task bar and so on.

You can manage but the defaults are really bad for power users.

Honestly Apple just needs to let me install a proper Desktop Environment like KDE on it. The unix base is decent, just give me more freedom.

To be fair KDE is also pretty wonky out of the box (basic stuff like turning numlock on boot is unnecessarily buggy or confusing).

you usually also need a bunch of extensions. And 50% of them are broken due to various if you try to use KDE builtin extension thing.
