Which is better Canon EOS Rebel T3 or Nikon D3100?

I want to know which is a better camera for a beginner a Canon EOS Rebel T3 or Nikon D3100?

Take your pick. Hold each one in your hands and choose the one that feels right to you. That's the better one.

You're comparing apples to apples so there's no "better"… Different yet, but not better. These two companies produce the best equipment in the world so pick one already.

I would suggest you buying Nikon D3100
Much larger screen
Lower noise at high ISO
Higher resolution movies
Better color depth
Better image quality
Supports 24p
Video autofocus
