When the 5DII came out, it was revolutionary (video), but outshined in EVERY other area just about, by the D700.
Now the 6D is the lightest FF DSLR, with built-in wifi/gps, and awesome low light "single point" AF- but technically it is outdone in most areas by the D600.
Had it not been for D600's oily sensor problems, mixed bag of build quality/feel, and new generation nikon control layout, I would have gone with the D600 over the 6D.
Overall, I'm very happy with it. It is an easy camera to use, with an amazing sensor.
The highlighted sentens is not true in my opinion.
D700 was and still is an excellent camera. I thought about purchasing it instead of the "coming" 5D II.
A nice Nikon guy told me to wait for it. He was waiting for D700 (FF) since 5D appeared. I waited for two months and was happy I did not purchase the D700 (I do not do video).
I shot Weddings with a collegue (D700) who is an excellent photographer. But the 5D II gave us more hits in focus, using center point only, than D700s focus system. And better IQ of course (D700 was same on pixel level but at half resolution only) and more natural skin colors, too.
This has changed now. Nikon is on par or even better (in sensor technologie). But imo it is marginal.
