Unsharp masking isn't a reasonable way to compare the scans, since
this doesn't get to the root of why there's a difference between the
results from the two scanners.

A good test would be to turn off "Device|Auto focus" and
manually vary the focus on the Nikon.  This will give a good
indication of whether the clarity of the dust spots is related to
the focus of the scanner.
