I bought a new laptop a couple of weeks ago because the keyboard on my 2012 model was getting flakey. It prompted me to upgrade to 11 during the setup process so I did. So far no issues, and it isn't so different that I had problems figuring anything out. My only complaint so far is I was running Office 2013 on the old one and decided to go ahead and make the jump to the subscription version of Office 365 so I'd be using the same thing I use at work. When I did that my old copy of Visio, which I like to use for playing around with floorplans, wouldn't work any more so I had to upgrade that pricy piece of software too. But that isn't a Windows 11 issue it is an Office issue.
