Not sure what you mean by "best", nor by "wide". One of the best is the 24mm f/2.8 Ai-S, which has Nikon's Close Range Correction system of floating elements, and is one of the sharpest wide-angles for closer-distance work at apertures like f/5.6 to f/11--it is simply outstanding!!! On a 1.5x body, it's not very wide, but it is "semi-wide", and it produces a small amount of apparent perspective distortion when photographing people at normal indoor distances. Not a "lot" of apparent perspective distortion, but "some"; and yet enough, as they say, for artistic purposes. That would be my choice as "the best wide-angle prime for Nikon". Failing that, the 24mm f/2.8 AF-D is "okay", but not as good a lens as the older, better-designed, more-expensive Ai-S manual focus model.
