I can tell you my experiences.
After my first 6d, I thought the same thing. The Af was atrocious. It was missing possibly 95% of shots. I dont use focus/recompose. Canon switched the body. The new one - my current one- works a lot better and is 'stable' in the Af department.
When testing the 2nd body, I canvassed the web and review sites for 6d images- straight from camera- as well as 5d3 raw files. What i found was the overwhelming majority of 6d images were in fact not anywhere close to sharp. But they looked good. Similarly, none of the 6d shots i see are anywhere as sharp as even the 5dmk2 shots Ive been seeing on the web for years.
I sent the second one in along with my 24-105 before my vacation to japan, and it did well- the shots on average are well focused. Im now comfortable enough to carry it around, and did a few shoots with it since then.
So even though its better now, I cant say that Im happy. I still dont have the sharpness or 'wow' factor from the images i expected to see with my 6d. The outer points work, but they fail just as much.
So at some point i will sell it and trade up.
