What is the Value of the Windows Insider program?

When Windows 11 was released, I quickly joined the insider program (Beta). I just as quickly left it again, as I saw no advantage for me personally.

Last week, I decided to give it another go.
No prob joining and receiving and installing the latest Beta.

Now. No sarcasm or criticism intend. Please, no "under the hood" answers.

What should I be looking for after Ms's two years of development? I finished up with a copy of Windows 11, absolutely identical to the original which I have installed a long time ago. A thorough search through the settings revealed nothing!
