I'm not a Windows user but from experience, I would always wait a couple of months before downloading a major upgrade.
Almost certainly, there are going to be updates and fixes and it takes a while for these to be finally ironed out. If I was thinking about going from 10 to 11, I would definitely wait for all the minor problems to be fixed.
From what I've heard though, Windows 11 is supposed to be very sleek.
