I like Ubuntu the most from a GUI perspective. Sometimes I feel the urge to uninstall Windows 11 entirely and replace it with the latest version of Ubuntu or even dual-boot them side-by-side, but then I realize that I'm way more used to Windows than Ubuntu. Also, there are a lot of apps and games I won't be able to use on Ubuntu.
I have a Bachelor's in Computer Science, so I'm familiar with Ubuntu, but as I told you before: I would choose Windows over Linux in the meantime.
I don't think any operating system would replace another any time soon.
