I used to run MacType a few years back (on a Win7 machine), and it was really nice having unhinted subpixel rendering, but I couldn't deal with the random issues that would crop up when a program didn't like the presence of MacType. I am firmly in the Mac font rendering camp, even as a Windows user, as I prefer my font glyphs to be accurate to the outlines, as opposed to being forced to the pixel grid. The thing that makes it hard, is when you don't hammer the glyphs into the pixel grid, the spacing becomes different, so even if you make it render unhinted fonts but with the metrics of the hinted version, you now have horrible keming left and right.
