Two different classes of camera...I'd like to know why you pick these two instead of a say 40D?  40D is a way better camera then both 5D or 450D except for the FF.

What do you do with your camera? I mean do you really need FF?

Do you do low light photography?

It's hard to help without more info....

I think people are over exaggerating the FF factor.  Yes, it's nice to have and blah blah blah
but if you're a sports photog then a cropy body is just as good.
