I'm running the public releases of Catalina on three of my four Macs now, and it runs fine.
As I said in my post, I am out of the BETA program, and I am a long time BETA member and Apple developer person.
It's not the same as years ago, Apple BETA releases crash way too much; and my hardware is fine, MacBook Airs, MacPro, MacMini. I don't run macOS on anything but Apple hardware.
I don't have time to debug Apple's beta releases anymore and in my opinion, the bugs are far more more serious and frequent the longer time has moved into the post Steve Jobs era at Apple.
Steve Jobs was a visionary, innovated, brash, perfectionist. I miss his leadership at Apple.
But that is just me, I guess ....
