which ever you choose you can´t go wrong with any...

my preference is Canon.... as I´ve had Canon since ever.... I had film, digital... and now looking forward to another one.. LOL...

Nikon is a great choice too... but it you already own a Canon and have lenses and such you can use them in a newer one without having to buy lenses too.. or you can sell the whole thing and get Nikon equip.

go try both at a store and see how you feel about them... they are both great choices...THE best choices
