Canon F1 is by far better than the Nikon F2. It is more reliable. I have two Nikon F2 Photomic with the hell expensive DP2 finders with one of them needing calibration and the other not working at all. On the Canon you just put the lens on it and you are ready to go, while on the Photomic you need to set the finder and the lens on 5.6 then set the lens at maximum aperture and provide that feedback to the finder.
Also, most of the Nikon F2 develop problems with the slow speeds.
The only plus that I could count on the Nikon F2 is that for the meter it does fine with 1.5V button cells. Nothing more.
