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.
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.
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 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.
