I installed Catalina a few months ago on a 2017 iMac. It's fine. The only "issue" is it may be incompatible with some of your software. In my case, the only affected apps I particulalry cared about losing were Microsoft Word & Excel, but at a suggestion by someone at mac-forums, I downloaded SoftMaker's free office suite, and that works fine and accepts all my Microsoft docs.
The OS seems to me faster and cleaner. It just feels better. It's the first upgrade for me since Leopard that really feels different. I like it.
