K3 may be a better choice for other reasons and for some applications, though... but let's not generally misrepresent.

Well, you say it is, I look through the pictures, and say no it's not. I don't see any differences below ISO 1600 I can't correct in post processing.
So once again, you say tomaitoes, I say tomaatoes. I extensively investigate the 6D at one point, compared images looked at test shots, checked out what IR had to say about it etc...so I'm not buying it.
To me the 6D was significant, because it was the first FF produced, that produced the same IQ in terms of resolution as a top of the line APS_c of the day. The old thing about your worst lens on FF is better than your best on APS-c is history. At least in terms of resolution, the K-3 and D7100 will achieve the same resolution with the same lens as the 6D does. They need 4 more Mp to achieve that, but they are there. The camera manufacturers from my perspective, have finally produced an FF camera, new off the shelf that has to compete with APS-c head up feature to feature, and isn't any better in IQ, and isn't really comparable in features. . You have to give up features to get features. So in that sense the cameres are pretty much equal, but only in IQ One is better some ways, one is bert in other ways, some will be better for one type of photographer, some will be better for others.
IN features, it's not even a contest.
Frame rate, shake reduction, and many other features mean you give up a lot to look at a 6D
But in resolution, the thing that has always been big in the full frame arena, they are equal. Being interested in FF mostly for resolution in landscape, trading my K-3 for a 6D wouldn't give me better landscapes, but it would cost me my high frame rate and the advantage of smaller pixels in wildlife images I get with a K-3. I honestly wouldn't use one if someone gave it to me.
For someone completely fascinated with the narrow DoF thing it might be a good camera. But what they would give up to get that, for many would be prohibitive.
For landscape guys, and for many others, the bottom line is not, what gives me the the best high ISO image. It's what gives me the best image, period. Without qualification. That would be the K-3 on a bright sunny day at 100 ISO with a good lens. That is the ultimate best image. And I doubt the 6D can beat it. It might equal it, but why would I go for equal, when there is so much other stuff I'd have to give up, and pay more money for the body.
