That pretty much sums up my experience.

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...

Well, that sounds like a good reason to be happy you updated. :)
