The breakdown is, it depends on the scene. For example, if you are shooing landscapes with trees at 20*30, and cannot see the difference between a 1DII/1DIII and a 5DII/III, then you need glasses.

If it is a portrait shot with a 1.2 lens, most cases it is much harder at NORMAL viewing distances.

Double resolution is major. But I can see the difference on landscapes between the 5D3 and the D800(E). And that is not double the resolution.  Since I owned both the 1DII, 1DIII, 5D2, 5D3 and a mix of 20D, 30D, etc over the years, I can see it.  I have a 20x30 print, ISO 100 from my 1DII on my wall and I can see the pixillation in this pic. I do not see it at all in my 5D3 print, ISO 100 from the same area (I shoot a lot of my portraits in the same 3 locations, so I can see a progression from one camera to the other, over the years.)

I think you need to talk to people who have owned all 4 of the camera, and ask them about the prints from the same locations.  Different pics do not count, since all scenes are unique.

I currently have a show of 38 20" x 30" prints appearing at the Viewpoint Photographic Art Center in Sacramento. Most of the pictures were taken with either a 5D MKII or 5D MKIII. However, some of them come from the Canon 1D MKII and 1DMIII which are not full frame and have about half the number of pixels of the 5D cameras (8 & 10 megapixels vs over 20 for the 5Ds).

What I noticed is that I could not tell which pictures were taken with the lower pixel count 1D cameras. They do not stand out as obviously inferior. In fact all the pictures look good and are indistinguishable in terms of sharpness or resolution.

Now I'm sure that there are benefits of the 20 megapixel cameras. And I do own two of them. But my point is that real life photo situations with large areas of bland texture or out of focus areas do not reveal such differences. This is a bit of a surprise for me but a reassuring one.

If you happen to live in the Sacramento area, you're welcome to look for yourself. The gallery is at 2015 J street and is well identified with signage.
