I installed it on one computer, and no problems (other than the freeze during install that so many people had). However, that’s ignoring this question:
> I didn’t even have to debate too much whether I should upgrade or not. The answer is no. The reasoning behind it is quite simple, actually, and it boils down to this: what Catalina takes away from me is more than what it gives me.
And that seems to be the case for me, even though I have no Catalina problems. Lost MS Office 2011 on that machine. Gained... I can’t think of a single thing off the top of my head.
Let's hope it was all worth it and Catalina is indeed a transitional release that serves no other purpose than laying some under-the-hood groundwork for the next release.
I wouldn't say "wish I didn't upgrade" because both my 2018 Mini and 2015 MBP are working fine, but I agree with the general sentiment that from an end user perspective there really isn't any reason to upgrade, and apparently many cases not to considering the issues reported by others.
Now that I'm typing this one thing that Catalina improved comes to mind: I have less issues driving my 5K LG screen through my BlackMagic eGPU. With Mojave, rebooting or losing the GPU connection would regularly result in black screen, and only a complete shutdown and cold restart would fix it. Don't have this problem anymore...

Thus, wish I hadn’t upgraded.
