Personally I’ve had zero issues upgrading to Catalina, it seems to perform better than Mojave for me, and more stable too.

At this new role, the 2019 13inch retina MBP I was given seems to have one or two kernel panics a week on Catalina.
Also, I haven't noticed this other issue lately, but for a couple of months my laptop screen would flicker/distort and times for a moment or two; have not noticed that issue since setting up a home office with external monitor for obvious, current reasons.
Thanks, I laughed a little at that.
People have been saying exactly that for as long as operating systems have been on disk. I was thinking just a few days ago that I must have installed OS/2 50 or 60 times in its day.
I can't calculate the number of weeks of my life I've wasted babysitting clean operating system installs.
You're right, it shouldn't happen. But we're decades away from that being the reality.
The Catalina beta was a sh!tshow on my MacBook Pro, as was the first (upgraded) release. A fresh install made most of the issues go away.

It's one of the most recent reasons I have yet to update to Catalina.
