There seem to me 3 issues.
The first is are you (as distinct from anybody else) happy with the price difference and the significantly different set of features. Price seems your main concern.
Second, as I explained earlier, you are shooting at two different apertures for DoF and possible sharpness and need to stop down the Nikon two extra stops compared to the Artisan to get comparable depth of field with a possible different Nikon resolution in the bank note comparison
Additionally exposure differs by about half a stop.
Third zooming in on my calibrated monitor on a relatively small image (a forum posting limitation) there is a moderate though useful resolution advantage to the Nikon - that might change if identical (for exposure) apertures are used.
If you want to primarily get to 2:1 and mainly work from a tripod with manual focus the Artisan has a good feature set.
If you want to limit to 1:1 without accessories, to sometimes hand hold with VR, to have AF, to have what is known to be a good portrait lens, to do focus stacking via the camera menu and based on your posted tests to have the highest resolution then the Nikon has a good feature set.
