The F-1n came out in 76 and the New F-1 in 81, the Nikon F2 came out in 71, so the F-1n/New had quite a bit of time to get "sophisticated."
I think the F-1 is a fine camera, but I don't own Canon FD gear, hence my use of Nikon and other systems. I think the F2 is probably close to the perfect camera, awesome build, etc. for that time and I'll use one any day of the week without a thought. It's probably more accurate to compare the F-1n and New F-1 to the Nikon F3, rather than the F2. Honestly though, why even put them into a comparison test?
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
