To put it another way, I have never met a person who was highly competent with using Windows and also highly competent with using a Unix-like OS (Linux, *BSD, etc) who still preferred Windows.
A computer/operating system is a tool. And like any tool, it's usually best applied to the jobs that suit it. I don't think it's rare to be proficient with more than one tool, and generally prefer one over the other when you have different uses for each.
For instance, I don't prefer my shovel over my rake, unless I happen to be digging a ditch.
