Used the Nikkor 35mm 2.0 AIS for many years and consider it a solid "good", though now not my favorite or best. Distortion with that lens is certainly not a "huge deal", but is present and may be visible in critical applications (architecture, reproductions, etc.).
Same goes for the Nikkor 24mm 2.8 AI/AIS.
My favorite 35mm lenses in order of preference (roughly, as what's important can change):
Zeiss 35mm 1.4 (Rolleiflex)
Leica R Summicron 35mm 2.0, last version (Leica R)
Leica M Summicron 35mm 2.0, Mk. IV (Leica M - Yes, I find the SLR R Summicron better than the rangefinder M one...)
Leica Elmarit 35mm 2.8, last type (Leica R)
Zeiss 35mm 2.8 (Rolleiflex)
(Up to this point I consider these lenses as being close to "perfect")
Pentax 35mm 3.5 (M42 + K?)
Schneider Curtagon 35mm 2.8 (M42, Exakta)
Nikkor 35mm 2.0 (Nikon)
Nikkor 35mm 1.4 (Nikon)
Jupiter 12 35mm 2.8 (M39)
Voigtländer 35mm 3.4 (Bessamatic, M42)
Zeiss Jena 3mm 2.8 (Exakta)
Nikon 35mm 2.8 AI (Nikon)
& Several others...
