I hear the complaints about Tahoe but I don't fully understand. For me (and I consider myself a power user, and I've been using macOS since ... Mac OS X Jaguar. I've been through it all).
Tahoe to me is stable, the Liquid Glass doesn't get in your way either. It's pretty elegant. My machine is still insanely fast.
The other day I saw an article about not being able to resize. I can't reproduce that either, it's easy to resize windows in the corner.
What got me to go back is mostly UI and design related, but it was mostly stable. I just can't stand the new design. And Tahoe to me felt like I was less in control of the system compared to earlier versions.
On Tahoe I hardly notice liquid glass. The Dock and some buttons I guess. On iOS it's much more in your face, but I am getting used to it.
Seeing the glass buttons in front of a running movie is quite impressive.
