Maybe I should do this in pictures. You guys are simply not getting what I've said.

If I take the Nikon D800E images down to the same level of magnification as the SD1M images, the Nikon images, already cuttingly sharp, are even sharper and more detailed.

If I go the other way, and uprez the SD1M images to match the same screen size magnification as the Nikon images, the Sigma images lose detail significantly.

Spot on, Ron. I've been doing some research on that very subject (re-sampling downward), using DPR's test images and slant-edge testing them with QuickMTF. I am finding that, irrespective of the camera, acutance is significantly improved with proper downsizing. Some folks will take exception to your "more detailed" but perhaps you mean more contrast.

I'm also finding that re-sampling downward gives slightly "better" images than the same subject shot with a lower resolution camera.
