Did you try the Sony in person as well? Ideally, you would be able to have the Canon, Sony, and any potential Nikons (like the ones Boogschd mentioned) right there to fiddle around with and try out. That said, if you've tried them and the cameras seem pretty much equal in terms of comfort and ease of use, I would go for the Canon because there would be a larger variety of lenses and gear available compared to Sony. I don't have personal experience with either of those cameras, though, so that's about as much info as I can offer.
