I think what you should take away from Jimmy's comments is that the "higher end" camera is worth the added expense, not necessarily that canon is better than nikon. As people have said above, you'll never get a straight answer when it comes to that arguement.
Now, that being said, I personally would spend a little more on good glass (lenses), and get the cheaper body. You can always upgrade later if you get really into it, and want the added bells and whistles. FWIW, I started with a Nikon D40, got really into photography and later upgraded to a Nikon D90. I love the D90, and don't plan on getting a new body until that thing breaks. For now, I'm spending my photography money on better lenses.
