Any 28-300 is extremely versatile in terms of focal length range but they all have significant compromises somewhere in order to achieve that range and be affordable. You'll find that sharpness is lacking or even the resolution, especially away from the centre. Some focal length / distance combinations will be worse than others. Vignetting (light fall-off) will be obvious and correcting it will increase noise. It's most likely to be sub-par at the FL extremes (28 and 300mm) where it is most likely to be used.
A D800 is likely to get the best out of the lens but the lens will certainly not get the best out of the D800.
For some of us it may be the best single lens to have if we could only have one lens and did not have a single purpose for it, but it will not be the best or even a great lens for any specific focal length in its range.
The VR will let you shoot hand-held in lighting that non-VR lenses will not cope with. The smaller aperture is often needed for some DOF in which case the benefits of large-aperture lenses without VR are partially lost in poor light. Obviously, YMMV.
Colour rendition is largely irrelevant because errors in white balance will swamp any rendition errors. Some will disagree but most of us do not know what the correct WB should be for each shot and so we fiddle to make it "look good". Studio work would be different, as would any controlled lighting scenarios.
AF will be reasonable in good light but in poor light the smaller aperture will starve the camera of light and contrast and slow the AF down compared with using brighter lenses.

Thanks a lot for such an informative review... I am honestly not expecting this to beat primes or pro zooms but I am trying to see how it compares it with other "general" lenses like 28-105, 24-120, 18-200 and the like. It's not going to be my only lens. I have Sigma 12-24, 105 2.5 AIS, 50 1.8G and planning to get the 28 1.8G. So this will be for those "I don't know what I am going to shoot today" days.
I saw samples on flickr and here on FM and I felt it had better sharpness than it's DX equivalent the 18-200
As for KR, well I read the review and thanks for sharing it I like his simplistic take on things though he can be really contradicting at times
