Um, you are asking the difficult/impossible. I favor the Nikkors,
since all of the large format Nikkors are excellent, but all of the
major lens manufacturers make some lenses that are their equal, so it
depends on the particular FL and speed of the lens you are looking for
whether there is a discernable difference in lens quality between similar
lenses offered by the various manufacturers - but at the apertures you are likely to use with large format lenses, it is unlikely that you will see
much difference among lenses except maybe among the super-wides.
Hope This Helps
