That's what I was about to suggest. You might find one is irritating to use for whatever reason and go for the other. However, do try to spend as long as you can playing with them. What might seem like an irritation to begin with will either grow and become intolerable, or you might find that when you get used to it, you can never go back. I found a few things that irritated me about my EOS 3 when I first got it. My previous EOS 5 had been easier to use in ways, and seemed to get better results for less effort. But the 3 is a professional tool rather than a serious amateur camera. It forced me to pull my socks up and lift MY game in using it, putting more effort it. And the results of that are things that it would have been very hard to achieve with the EOS 5.
