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.
