The F-1N and F-1(n) certainly have their advantages, particularly for shooting in manual mode since all the info is in the viewfinder. However, for aperture or shutter priority, the A-1 is a bit better because both aperture and shutter control are in the same location and can rapidly be changed with a single finger. Plus, it is a "lightweight", especially with the motor drive; it's a lot lighter than the F-1s with their respective motor drives. So, it's all a matter of what suits your needs - like always.
