What you mean by sysadmin GUI things? Linux is so much simpler, you don’t need any GUI to configure it. And probably there’s no point in that. Actually, there is a way to configure it using code (see Ansible), which is better (I’d say).
I believe this way of configuring is much more efficient. Yes, you have to learn some new things, probably even new paradigm. But once you done, it stays mostly the same for long years, and is dead simple. I am, being Linux user for circa 15 years, see administrating Windows with dread. And most Windows sysadmins I know personally, when I tell them about Linux, and they react like it’s some hidden obscure knowledge they have to spend ten years studying it. Which is vice-versa actually. I cannot imagine what that is, to be a Windows sysadmin, especially supporting all this mediocre engineering.

It may be better, but it needs change and retraining.

Me too. I do not much like using Windows either and it seems to be getting worse.

Partly FUD (lots of people make claims like "you have to compile your own software to use Linux") and partly because people hate change, and partly because it took them 10 years to learn Windows (many years ago) and they expect the same again.
It took me many years to accept Unix logic (macOS and Linux) too, but mostly because my first system was Windows.
For some reason, things like disks, C:\ and D:\ were logical to me, while I couldn’t grasp why cannot I put my files into root directory, and I’m forced to live in a subdirectory (/home/user) instead. It takes some time to re-learn, but I’m looking back with some dread. Things I accepted as simple, are actually unacceptably complex.
