Avoid the N50 - too limiting. The 6006 is excellent, though noisy.
Never tried the N70. None of these has DOF preview. If AF is not
primary, I would look for a used N801/801X, or F3.

The 24 is identical to late AIS MF design, and quite good (though the
20mm f2.8 is better on the edges...). The non-D 28 AF is quite poor;
the D version is much better, but not as good as the MF 28mm f2.8 *AIS*.
The 24 is probably the better of the two lenses you named. I generally
prefer the build-quality and optics of the MF lenses in the under-50mm
range... (and the build-quality in the longer MF lenses, too...;-).

The F3 is a much better choice for this, due to its accurate,
sharp-all-over, distortion-free VF. AF is unnecessary for landscape
work, but sharp lenses (and DOF preview...) is.

The 105 AF is difficult to focus accurately near infinity, and
(probably for the same too-fast-focus reason, is often poorly
aligned optically at infinity - stopping down would help, though).
The VF of the N90 is not adequately sharp for good MF, I find.
The 50 is excellent. The 400 Tokina, though....;-)

It may be quite sharp in an ideal sample, but I find a lot of
sample variation in the Nikkor AF 35-->X zooms, so I avoid them.
The 35-70 f2.8 is generally the exception. I would go with the best
primes for landscape work (16mm *f3.5*, 20mm *f2.8*, 28mm f2.8 *AIS*,
28mm *f4* PC, 35mm f2.8 PC *latest version*, and almost any prime 50mm
and over, except the 50mm f1.2 and the 60mm f2.8).
