This is not the place to discuss about operating systems, and people expect from you to respect their preference.
Linux has its technical merits, and because of them it is the most used OS in servers, supercomputers and niches like web development, but it also has its weaknesses, and because of them it isn't the most used OS in homes or corporations.
OTOH, there already exists a Linux distribution which is more popular than Windows, it's named Android, you've probably heard of it. It is a disaster in comparison with Windows, it gets locked, bloated and abandoned by phone manufacturers, phones get declared obsolete ridiculously fast and people are left without even security updates, you don't even have the ability to "format" a phone unless someone breaks a vulnerability to gain root access.
People blinded by Linux usually overlook the disaster behind Android because they're too accustomed to focus their attention in the issues of Windows, but no OS is perfect and people will choose the OS that works better for them, you must learn to accept and respect their decision.
Jokes aside, I stopped fighting desktop environments and embraced Ubuntu's Unity some years ago, at the end I learned to appreciate it and nowadays I feel more comfortable with Ubuntu than with OS X.
I still prefer Windows over Ubuntu, but because I have added several utilities to my workflow like Everything Search Engine or WinSplit Revolution (now defunct), not because of Windows' own merits.
I just wish there could be a way to have OS X's hotkeys in Windows, since CMD + <anything> is more comfortable to press than Ctrl + <anything>. I also miss having the behavior CMD + Tab / CMD + ` and the ubiquity of CMD + ,
