Nope, it isn't, it's the same as the 5d2 with added low-light capability, read the specs: It has only a horizontal f2.8-sensitive line, i.e. if that cannot achieve focus it falls back to the f5.6 lines. I didn't understand that at first either, but Dr. Neuro explained :-) ... and this is my biggest grief with the 6d, it's anti-tuned for f2.8 lenses just like the 5d3/1dx af is tuned for them. It's made for the 24-105/4L (kit) and 17-40/4L (Canon did the sample shots with this)
And the center AF point of the 5D2 works well. The limitation of this AF sensor is in tracking as well as the peripheral points. Since the 6D center AF works at -3 eV compared to -0.2 eV on the 5D2 and -2 eV on the 5D3, one cannot draw immediate conclusions WITHOUT even trying the camera.
Another thing, ALL the cross AF sensors on the D600 are clustered around the center. Of what use is that?
Actually, all full-frame cameras with optical phase detection AF sensors are clustered around the center. D600 is slightly more so... take a look at the comparison between D600 vs D800... not much difference. I use my D600 to get enough negative space, plus it is real plus when it comes to action(when things are centered):
