Ok, I decided earlier than expected. I made the mistake of going to a shop and trying everything out. 
Just in case anyone is interested:
I tried both the D600 and the 6D with some lenses. I did not expect that the ergonomics do feel that much better on the 6D. I had a Nikon D90 some years ago, but still the 6D was much more intuitive than the D600 now. Also the grip on the 6D is a better fit for the right hand and the camera is noticably lighter. Considering the body alone, I like the 6D much better and I think I can live with the small limitations in compatibility with my MF lenses.
Regarding lenses, I think I will add a 35/2 IS or a 28/2.8 IS. Both felt like a very good match for the 6D. I also tried the f/1.4 flavors of both Nikon and Canon 35's on the respective cameras and also the Sigma 35/1.4, but those lenses are just too huge and heavy.
The salesman was quite funny. He tried to convince me of Nikon all the time for strange reasons. He said the glass in all Canon non-red-ring lenses is made of plastic while almost all Nikon glass is made of glass. Yes, he really referred to the glass inside the lens. He ran into problems with his argumentation line when he noticed that all recent Nikon lenses have the "G" in their names, just after telling me that the G was the equivalent of the Canon L. His further praise of Nikon was without any reasoning. I was prepared to pay a bit more for a good counseling, but after this I went without having bought anything.
