If I was a leisure photographer...I would just get a D800 or D800e. IMO, they have the best of most worlds in Canon vs Nikon camera BODIES (note this important point) in that they have the massive resolution for print and crop, enough fps for general purpose shooting, far superior shadow noise, and high ISO noise comparable or nearly comparable to some of the best and most expensive full-frame cameras currently available, plus a very nice feature set.
The downside to Nikon...their live view is comparatively sluggish, it takes two hands to adjust ISO and similar common settings, the Caucasian skin tones are more orange/green than the magenta...and they can't use Canon lenses. Canon has a better lens selection even though their ultra-wides are not all very good or are very poor values (14L II is good but overpriced, 16-35L is just plain soft in corners).
I wouldn't want to try to compare a 5d2 to a D600, since the primary differences will be downgrades except the shadow noise and more AF points.
Then there's the problem of trying to get a D800 with NO af problems. So far I have had one out of four D800s I've tried that had no AF issues. The other three had varying levels of outer point accuracy problems.
Nothing was so aweing about a camera I have purchased since my first full-frame experience with the 5d (the "look" was just so great compared to crop cameras)...as the shadow recovery of the D800. It was simply incredible. I am a very level, mellow person, and anything getting a real rise out of me has to be seriously a huge improvement. The D800 shadows really were just that good compared to anything Canon. That is the ONLY reason I have tried FOUR D800s out (two since I sold the one good one I had purchased)...because the shadow recovery was a kind of magic, a lifesaver, and a spoiling convenience.
