I am very happy with my Canon. I can't really say it's better than Nikon, since I have only just held a Nikon a couple of times. The Canon felt better in my hands when I tried them both at the store last year. I have read some things that have made me glad I have a Canon, though they may be trivial and/or just a matter of what I'm used to. For example, just today I learned that the exposure meter is "backwards"
on the Nikon, compared to the Canon.
So you have been to the store and really spent some time test-driving the cameras? I kept reading that that is very important and I found that only when I did that was I able to get anywhere near making a choice.
Good news is, I bet you'll like whichever one you choose! You'll learn how to use it and love it. They're both great cameras.
