Which dslr camera to buy?

I'm gonna buy a Digital SLR by next week, the question is that i still hesitated and uncertain with my choice between the Nikon D3100 and the Canon EOS 550D they are both great that's why am hesitated between both i know there's a difference in price (well the canon is way bit expensive) but that is not the case anyway! So waiting for answers. Thnk u all

Being a Canon guy I only recommend what I own and therefore know. I have two Canon dslr cameras and both are excellent. Just be sure you get some good lenses regardless of which camera you choose.

Also know that buying camera gear based on price is never a good idea. However also know that both companies make excellent gear that will last a very long time.

The only real difference is the size of the sensors themselves. While both are classed as APS-C - approximately two-thirds of the area that you can expose on any frame of 35mm film - technically the Nikon DX sensor is a touch bigger. What that means in real terms is that there's the potential for a higher dynamic range with the D3100.So one might find that you get slightly better results on shots with a wider scope of exposure required. As it goes, Canon may have better processing power to take care of that problem anyway.
