@Rob,
My remark is I think the whole basis for this discussion.
When you are shown an internet version or a cover of a magazine you can't 100% sure tell which camera is used, especially in this time of photoshop.
Although in some cases you can.
HOWEVER....
There is much more.
Think about how to get the shot, how the image holds it's own in postprocessing, how the image is on a large print for a gallery etc.
Billboards are low quality, but gallery or fineart prints are a different story.
Let's go back to the cover.
You can't tell by the cover if you needed a MF or DSLR, however if you would have started at the very beginning of the process with a MF or a DSLR and would have take the whole workflow the same way you will see a difference in the cover.
The tonality of the MF will be different, as will the perceived sharpness, DOF and dynamic range be.
I'm just back from Belgium were I taught a workshop in a Castle were we mixed a lot of ambiant with strobes.
Because I'm shooting straight to a laptop on location people can see what's going on.
The think almost everyone notices during all this kind of sessions is that even on the laptop it's clearly shown that the MF camera holds the shadows and highlights much better than the DSLRs.
For example were in my shots the feet are still barely visible from the shadows and the highlights on the wall from the ambiant light are close to clipping but still show detail, the same setup on the DSLRs (a mix of Canon and Nikon) was different in these areas.
The remark I made was that in the FINAL product both will look great on a cover, and you will deliver a good product.
However when knowing the whole process you will see there is a difference.
You can make the DSLR shot look the same by just opening up the shadows a bit with a filler at let's say 3.5 stops under the mainlight but that's the point, with the MF camera I don't need to.
So I did not meant is as there is no difference on print, but I meant both are delivering awesome options and people in these kind of comparisons are often comparing one finished result to another but not from exact the same setup with exact the same workflow.
@Ray,
What strikes me as odd is that you do respond to people on topics that DSLRs wins like high-iso, better displays etc.
But you TOTALLY ignore the facts like higher sync speeds, waste level finders, changing backs, cameras etc.
In other words you have your mind set and are stuck in a one way street and ignoring all the answers you ask for, except the ones you can turn the other way.
When I think about it I will do a side by side shoot with the 5DMKII and the Leaf AptusII 7 when we're on location again, but it can take a while, we have a lot of demos etc. coming up so little time to play.
