Seen through, say, a drum scanner...or a very high end CCD scanner.  Take
every factor out of it you can...so both are on equal footing and only the
ability of the film to retain sharpness is at question here.

Identical images, shot at the same time from the same angles etc.

Assuming a very controlled scene, such that the only difference is in the
actual ability of the film to maintain image sharpness.  This SHOULD be a
very very basic question, not related to anything but the film, assuming
both are processed to the highest standards.

OK, Laurie, do you have an answer ;-)
