I had to get a new computer and opted for the new Windows Surface Studio, which came with Windows 11. At first I was annoyed, but it was primarily because it's not Windows 10. After a few days, I fell in love it it. As RC said, it's super fast. And it's also a little more intuitive. Although, it does annoy me that Windows seems to think I'm a idiot with certain things, but overall, it's a great OS, a lot better than 10.
I wouldn't upgrade if you have anything big planned, but if you have most everything done and have OneDrive set up, you should be good to upgrade. I've even seen people upgrade old machines and raving about the unexpected performance. Overall, everything works better together. Yeah, there are some bugs, but I haven't encountered any of them.
If you're on the fence, or just trying to find excuses not to upgrade, I would say put them aside and bite the bullet. It's definitely worth it.
