I don't know much, but enough to maybe answer that question.
I was going to tell you to ask in the photography section since there's some real knowledgeable guys in there, but I don't think you'd get anywhere asking them because Canon vs. Nikon is basically like Mac vs. PC. They're both good and compete well, it just depends what brand you want to buy.
The Canon does have a few more megapixels and it seems like the regular price is a bit higher than the Nikon, so that might be the better choice. But I'd still go Nikon since I'm a fanboy.
