There is some strange painterly effect going on with the IQ180, I wonder if that results from the processing applied by the back to the raw files to reduce aliasing?
I believe you are referring to the look generated by their method of up sampling the IQ180 to match the scan resolution of the 8x10. I don't suspect you would note any such effect on the image when viewed at the original 100% pixel size. (I'm not saying I think the method chosen was unfair - there are many ways to approach such a comparison and I think they've selected a perfectly fine one)
In general this test shows what I would expect and have posted many times before: the 8x10 film shows a modest advantage in absolute resolution (on subject matter within it's DR) over a single frame from an IQ180 when enormous care is taken to get the most ouf the 8x10.
In practice 8x10 is extremely difficult to get the most out of every frame, and the only advantage I see in these comparisons is in the extremely fine detail when printed/viewed large enough to view those details. The color, tonality, DR of the IQ180 all strike me as excellent in these comparisons. It should be noted this comparison is of default rendering; the raw files the IQ180 raws could be pushed around fairly significantly (color, contrast, dodge/burn, etc) and still look great.
As Bernard states you could easily overcome the modest resolution advantage of the field shots with as little as one additional IQ180 frame, especially if your desired output is wide-aspect-ratio (e.g. 16:9, 2:1 or other panoramic). A two-frame stitch on a camera like a Cambo Wide RS (static lens - moving the back only) takes less time than it takes to load a single 8x10 sheet of film.
Or give the camera to Bernard and he can take a 16-shot long-lens pan-and-stitch :-). Just be careful to get the camera back afterwards.
