While I, too did not see what you described ... used the bitchin Zoom-thingy to peer at fonts:
it appears to my un- typographically-tutored eyeballs that Your fonts are more, er granular than even the super-sharp iMac ones.
That is, the apparent-sharpness of the black/white edges prolly goes to iMac, but: there seem to be more 'elements' (lines, curves) -per-character to yours!
(iMac default that is; dunno what else might improve on that. Yet.)
I expect that Peter and others have some views on which be the bitchinest fonts ... to use a technical term which only we epicures know.
Posit:
Apparently the eye/brain weights the really-sharp edge contrast higher than the actual %linear-fill of a given character ??
(I still need to sort out preferred sizes, font choices and other trivia which, together gilds the lily to a fare-thee-well. Poco á poco.)
