I am happy with it so far.
On Thursday I installed it on my backup MacBook Pro and Messages had problems - I eventually got that sorted out through a combination of restarts, turning Messages and iCloud off/on, and it' been fine since.
This weekend I bit the bullet and upgraded my primary MacBook Pro, which has some more apps running on it. Everything is working fine so far, I don't have a single app not working from a limited amount of testing with all and more comprehensive testing with my most important apps. Most importantly for me for me work, Parallels is working fine (I am on 16.1 and I use the Apple hypervisor as they recommend). All the Apple products are fine on both laptops now - Reminders, Contacts, Messages, Calendar, Music, Podcasts are all good. Handoff is working fine for me. Office products, Dropbox, Evernote, Lightroom, Zoom, HP tools are all are fine, and the utility/tech tools work fine. No crashes or spin reports so far. Time Machine backups working fine on both laptops. I have watched some 4K Youtube videos which looked good. WiFi speeds are good. The system seems just a very minor bit zippier to me. I have not heard anything from the fans other than when I knew they should be running due to a hard usage scenario.
I have seen a very few minor aesthetic things I am not thrilled with (like in Safari), but overall it's worked great for me so far.
