Citation needed on that one. I've only worked with a minority of Windows sysadmins who are as incompetent as you say. And yeah, of course a good unix admin can run circles around a bad windows one, but the converse is just as true. A good Windows admin can run circles around a bad unix one. It has nothing to do with the operating systems and everything to do with technical competence of the individual.
There are a LOT more bad windows admins than bad unix admins though. The floor of being a unix admin is so much higher that it already filters out a lot of people. There are so many MSPs and small businesses with a windows admin that does everything through a console its crazy. You are right its all about the admin, but on average, the average linux admin is far more comfortable scripting than the windows admin.
