Just upgraded to Big Sur from Catalina on my 2020 iMac i9 this weekend. It is so much snappier! Photos app in particular is so much faster with importing and facial recognition.

Thanks everyone on this thread for your input on this!
 
If you are brave you can immediately go for Montery as well, since that's also available right now. No clue how that works however. ;-)
