Canon t3, Canon t3i, or Nikon d3100? - 1

I'm an 18 year old girl who has a love for photography. I've been using a Sony DSC-HX1 and I'm ready for a DSLR.

The three cameras I've narrowed my search down to are the Canon t3, Canon t3i, and the Nikon d3100. And now I really can't choose between the three. I have basic knowledge on ISO and aperture and whatnot. The Sony camera I have now is pretty bulky, so I don't have an issue with bulky cameras. My original plan was to buy the Nikon and buy accessories with the extra money. But then people started telling me that Canon was "better".

So anyone who's worked with any or all the cameras, can you give me your input including pros and cons?

If this makes a difference any, I'm into landscape and concert photography. Also, I plan on minoring in photography in college and volunteering to take concert photos at a music festival in the summer.

Neither Canon nor Nikon are "better", slightly different but not better. This is the tool I use to compare cameras.
