Canon back then, compared to Nikon, were a huge manufacturing business. Much of the technology that was developed or designed for the Canon range of photocopiers, in the electronic stuff that is, found its way to their cameras.
Nikon by comparison, was a very reserved company, very small company and not really what one would call a leader in flashy technology being built into their products.
I don’t believe there was any Nikon camera body remotely comparable to the Canon AE1, it was so far ahead of Nikon bodies it was almost another world.
I used Canon bodies of the day, including the AE1, loved it, but I went with Nikon (stayed with them actually after seriously thinking of jumping ship) mainly because in this country, and many others, there were literally thousands of second hand Nikkor lenses to be had, compared to a minimal range of Canon lenses around second hand. Pentax had the biggest following and the biggest range of second hand lenses, but these were mainly zoom lenses, their prime lenses were few and far in-between.
I am a Nikon man through and through, but realistically, Canon has almost always had a superior product at any given time in the seventies, eighties and nineties. Before that time frame and after that time frame, I really don’t know as I was running rangefinders in the sixties (Canon

) and any new old stuff I get these days is usually 4x5”.
