In Europe our standard LF Lenses are almost exclusively Rodenstock and Schneider products.
However, we can get Fujinon lenses (rare) and Nikons (v rare)
However, there is almost no information available about them.
I understand that they are more common in other parts of the world.
I am looking primarily at a 210mm 75deg (ish) Lens either brand new or very recent
How do the Fuji and Nikon Lenses compare to the Schneider and Rodenstock products for sharpness, contrast, coverage, flare and how well do they age all relative to one another?
I assume the Fujinons are still in production
Are the Nikons still being manufactured?
There is a considerable price difference between the European and Japanese products which is too large to put down just to Yen:Euro exchange rates.
Thanks for the help

Correct apart from the last sentence. Inspecting the aerial image is not done with a groundglass, it's done with an optic. The aerial image is in the air, not on a surface. A telescope eyepiece typically focuses on the aerial imagefrom the main lens (aka objective). The aerial image takes the focusing surface or film out of the resolution equation and tells you just how good the image produced by the lens alone is. You can use a short focal length optic to inspect the aerial image to reach the resolution limit of the lens under test. You can take the groundglass off your view camera and inspect the aerial image with a loupe or other lens. Doing this handheld is possible, but to get down to the limits of the main lens and keep the planes of focus coincident, you'll need a way to hold the inspection lens square to the main lens, typically done with an "optical bench".IIRC it's the resolution the lens puts onto the image cast.
If you test it with film you've got the resolution that is the result of the lens and the film. The aerial would be looking with a loupe at the groundglass.
