Can you explain why you prefer the font rendering in OS X, or do you think it's just a matter of what you've grown used to? I think fonts in OS X look notably fuzzy, and the strokes all tend to look too bold.
Anecdotally, there's definitely some truth to it being a matter of what you've grown used to. I moved from an old Windows desktop to a Mac OS X laptop. I found the fonts on Mac OS X to be exactly as you described -- fuzzy, bold, fairly annoying. After a month of heavy usage, I stopped noticing it. When I visited my old Windows computer a year later, I realized I perceived all the fonts as incredibly jaggy, thin, and hard to read. But after a while (1 week) I stopped noticing as much.
I have a similar experience, but while I can get used to the blurriness, and after a while I don't notice it as much, going back is always a breath of fresh air. I imagine it like putting your glassses on - if I had to wear any - everything just aligns right. In fairness this happens on Windows as well if I have ClearType turned on, but not quite as much. Mind you the MBP has a higher dpi than my desktop monitor, and the bkurriness is still noticeable. On a different laptop that has Linux running, slightly higher dpi looks good; same with my Android phone.
No matter how long I use font aliasing, without some very high dpi my eyes just cannot adjust, cannot totally ignore the bluriness. Seems like I'm in the minority though.
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.
