This may sound rather ignorant, but the only reason I switched to Windows 11 on all of my devices is because of what are in my opinion visual improvements over Windows 10. Until something comes along that changes my mind - I'm not holding my breath - I will always be a fan of the Vista/7 UI. To me, those two OS's were the best looking thus far.
I have only been able to tolerate the UI with Windows 8/10. I realize under the hood, certain aspects of performance are inferior with 10/11 when compared to 7. But it is what it is. The OS has to have the support needed to run properly on my devices. So it's just the lesser of two evils at this point for me.
