You're dreaming!
I use my Mac for serious work, and have had no problems with Catalina. In fact, I've found some features (namely, sidecar), especially useful during work from home.

Wonder if they finally fixed this issue - my new MBP 16" has been experiencing a lot of kernel panics, while Apple Support could only tell me they're working on a fix.
