The primary difference is that Microsoft try to align everything to whole pixels vertically and sub-pixels horizontally.
Apple just scale the font naturally – sometimes it fits into whole pixels other times it doesn’t.
This means Windows looks sharper at the expense of not actually being a very accurate representation of the text. The Mac with it’s design/DTP background is a much more accurate representation and scales more naturally than Windows which consequently jumps around a lot vertically.
The two thing to note here arising from this “pixel-grid is king” approach are
- Windows does not scale fonts linearly as the rough line points out
- Windows scales the height and width but not the weight of the font
