The general consensus tends to be anything from the big four from the last 40 years is pretty good all offered a fast F5.6 design and a slower usually F8 design.
If you want the brightest viewing screen Nikon 90mm F4.5 SW or Rodenstock Grandagon F4.5 if you want the largest coverage Schneider 90mm F5.6 XL All of these are i bigger and much heavier that the F8 designs. Of the F8 designs the standout is the Nikon lens as it has the same coverage as the F5.6 designs but about half the weight.
Most expensive is likely to be the Super Angulon XL least expensive is likely to be a single coated F8 Super Angulon. Sometimes Fuji lenses from Japanese dealers can be really reasonable buys.
I have the F5.6 and F8 Super Angulons both Sinar DB mounted hence I paid peanuts for them relatively speaking. F8 lenses are no fun to focus on 5X4 screens in dim light I've kept the F8 one mostly because I had a suitable centre filter for when I wanted to us it on 5x7, subsequently I coughed up £200 odd for a suitable centre filter for the F5.6 about twice what I paid for the lens. You are unlikely to need a centre filter for a 90mm on a 5x4.
