I would say that is because you were really used to OSX. I was the other way around and really dislike the whole OSX UI experience.
I think it is just a bias based on our previous experience. Right now after moving freely between OSX, Ubuntu and Windows at different jobs for the last 5 years, I still prefer the UI experience of Windows (I only wish Windows would have a command line similar to Linux's one and it would be perfect)
