I’ve yet to see a single Linux kernel that is aesthetically pleasing on anywhere near the level of OSX or Windows 11… Or Windows 10… Or hell, 7, 8, and Vista lmao.
The fact that you’re using the terms “kernel” and “aesthetically pleasing” in the same sentence (and equating that to GNU/Linux “Proper”) leads me to believe that you don’t understand what a kernel is. Or really know what you’re talking about, for that matter…
