Share the same opinion - in fact, I downgraded back to macOS Mojave. In some ways, I guess the picture is clearer now on why macOS seems to have gone downhill. With their own ARM processors, Apple had to re-shift its focus away from Intel and make its OS work well on its own processor.

And of course, with their own ARM processors they can further dumb down macOS and lock it down like ios as that's more profitable for them in the longer run.
