I use 3 windows machines - Win 10 desktop (getting old, was originally Win 7, and can't upgrade to Win 11), my own Win 11 laptop and my work Win 11 laptop.
There are differences between Win 10 and Win 11, but given I started messing about on computers with a ZX80 and Commodore Pet, I'm used to switching to whatever MS have decided is the next bright idea, and Win 10 -> Win 11 is a fairly minor change, compared to some earlier jumps.
I can't really comment on performance, as both the Win 11 laptops have always had Win 11 on them, and are much more recent / high spec. than the Win 10 desktop, but certainly have no issues with either of them (except the HP work laptop which has HP's auto update 'feature' - it silently downloads and install HP specific updates, the pop's up a dialog to ask if you want to restart now or later - with now being the default. Great if you are in the middle of typing and hit any key just as it does so, which it taken as you wanting 'now'.....)
