Its a subjective impression: some people notice, most don't. Speaking only for myself, the original mechanical Canon F-1 gave the impression of being a step above every other SLR in fit and finish, notably better than the Nikon F and even a bit above the Nikon F2. The later electromechanical F-1 New was also very well built, but didn't blow me away like the older F-1. The Canon F-1 New feels (to me) about the same as the Nikon F-3: still nice, but a shade below the first Canon F-1 and the Nikon F-2. This is almost to be expected, as global economic forces and surging volume of camera sales in 1979 led to different efficiency-centered methods of camera mfrg that lost some of the "hand made billet" appeal of the older models.
They are that different eh.?
I have never held an original F-1 or F-1n.
My only experience is with the F-1 New.
It has been a few years since i sold my F3.
I cannot remember what i thought about its handling.
I did not like the Meter, View Finder display at all. So i sold the F3 and kept my F2-S.
The F-1 New is probably a bit more comfy in my hands. but i cherish both cameras equally.
I was at Sears Point 2 weeks ago for a "Vintage Auto Race".
LOTS of awesome cars..!!!
I was trying to photo a couple of 5.0 liter Corvettes.....when i hear a guy say, "Those are gorgeous".
I look at the guy and say "I am not really a Corvette guy, but the white and red one is great".
The guy says... "No i am talking about your Nikons".

He then called to his friend ..... Hey Sam, take a look at these beautiful F2's
They were both photographers, both about 65 years old and both enamored with my pair of Nikons
They had both given up on film almost 20 years ago.
I let one of them shoot a few frames out in the sunlight. We were in a garage at that moment, and the FP4 was struggling with anything but a wide open lens. They had gotten spoiled by the high ASA capability of a modern D-SLR.
As much as they loved seeing and holding the F2-S..........neither of them missed film or had any desire to be in a darkroom again.
Right then, a friend of a friend wandered by, and he was shooting a Mamiya C330.
They honestly had no idea that people were still shooting film and were MORE Shocked that some of us still have (and love) a darkroom.
