Funny, but I never liked the AF Canons as much as the equivalent Nikons, like the F4/5 or F100. Having said that, I really like the older FD Canon like the EF and go figure. Just a personal thing but just didn't like the plasticky sort of feel to the EOS 3, but there are plenty of people who use and love them so the cameras are fine, as are the optics. I imagine the EOS1 would perform and last just as well as the F5 for example.
