In addition because mac use commad+C, command+V for copy paste rather than ctrl+C and ctrl+V as Linux and Windows, you feel no different working from a CLI than from any other app. You don't have to mentally jump in and out of two different ways of working.
This extends all the way into GUI apps. Typical CLI commands keys work in all mac GUI apps. I can use readline keys such as ctrl+a, ctrl+e for moving the cursor e.g. Works even in office apps like Keynote and Pages.
It is very frustrating to not be able to use these Unix conventions on Linux!!
There are lots of little things like this which makes a superior experience IMHO.
