On the flip side I'm an OS X (and Linux) user and I tend to think fonts on Windows look spindly and have erratic kerning.
It really is a matter of taste and what you are used to. Also because antialiasing is basically a trick of visual perception, it wouldn't surprise me if there really are differences in people's vision systems such that some people are more likely to see heavily antialiased text as blurry, similarly to the way some people are more likely to object to low framerate video or get a headache when viewing stereoscopic 3D.
I can't count the number of times people have tried to correct errors in my Visio diagrams because they see bad kerning as if I accidentally included an extra space in the middle of the word.
I recently found that one can go into Options in Visio and change font rendering so it uses gray-scale. Then the kerning is just fine.
