KDE is not a OS, why you compare this with windows or mac OS , or inclusive a GNU/Linux distribution ?
in the future you can make a enquest between kde 4.3 an Ferrari f1

I agree. However, it would make sense to distinguish between desktop environments as they may change user experience quite a lot. So I would compare kubuntu as well (tempting to suggest other distros but then it wont be OS comparison anymore)
