Probably better to compare the Nikon F2 to the Canon F-1 or the Canon New F-1 to the Nikon F3 since these pairs are of the same era. Are you considering whole systems or specific prisms?
So far, with specific prisms. I only have the Canon F1n AE prism and the F2 - Uh, forgot the model number, but the original F2 prism. I would consider the complete systems against each other but don't have experience to do so. If you do, your input would be valuable.
