Originally posted by jsherman999 I hadn't read that review, but I'd have to second his opinion almost to the word - I've tried the Nikon 24 f/2.8 and was surprised at how bland and mediocre the output was. It was one of the first Nikon primes I tried, and It just brought home how good we Pentaxians expect primes to be - we've been spoiled, as it turns out!
It also made me realize why camera sales store folks (read: Nikon/Canon sales people) always seem to say "zooms are so good now there's no reason to use the old primes" - that may be because they're used to using lenses like the Nikon 24 2.8.
The Nikon 28 2.8 is kinda bad too. One of the most vaunted Nikon primes, the 105 2.5 AIS, is not really any better than the M 100 2.8 or Tak 105. In fact, it's not even quiet as sharp as those two.

The Nikon primes are much better lenses when used on a Pentax body
The bland coloring really gets a boost on the Pentax body.
There have been so very many iterations of each of these lenses, and different versions among those, that it really takes some research to determine which range of serial numbers among which versions are really worthwhile....
the AF primes are pretty bad though, Nikon doesn't really make any decent primes any longer (except maybe the 135mm Defocus Control)
The manual focus version of the 28 f/2.8 is way way better than the AF version, the AIS MF version of the 28mm f/2.8 is a very decent lens. I selected and converted this particular model over the Zeiss ZK Distagon 28 f2.8 that I got to try out. The AIS version of the 28 is a close focus lens (unlike the other versions), and while it isn't as great as the Distagon 25 up close, it isn't very far off either, they are pretty much on par at medium distances and the Nikkor 28 AIS is better at infinity, it's actually the best lens in my lineup below at infinity under 43mm, including the FA31, It practically has no distortion and very even out to the edges with very little CA, the coloring isn't quite as nice as the FA31, but color and AF are the only areas the FA31 beats this lens in.
If I hadn't splurged and purchased and used the Distagon 25, I'd be really happy with the Nikkor AIS 28. But it's the lens I go to now for landscape and architectural.
Definitely for $160-$200 or whatever they are going for, an excellent alternative to the Zeiss 28, and if money is tight, a good alternative to the Zeiss 25 or FA31 (if you don't mind manual focus)
Nothing beats the Pentax M and A version of the 100 f/2.8. The Nikkor 105 I have is just "different" so worth keeping, a little more muted in color and contrast than the Pentax, just as sharp though, (it keeps up with the voigtlander 90 and 125 there) but the slightly more controlled contrast and nice bokeh, makes it good for portrait and headshots, kind of like the opposite of the Zeiss 85 as far as contrast goes, so dull day, dull lighting, want it to pop then I'll use the Zeiss/Voigtlander, for subjects where I want a little more left in highlights and shadow detail to do more with later in post, or if it happens to be very contrasty lighting situations, I'll use the Nikkor 105...
