i havent owned other digital SLR cameras besides my nikon D80, but i have been very satisfied with it and have done some great pictures.
i have an old roommate that owned a canon 5d and it was a completely different experience (due to full frame) so i dont feel like comparing.
my impression is that between nikon and cannon there isnt much real difference in quality, more nuance than anything else.
the nikon cameras do perform better(less noise) at higher ISO numbers, but i must admit that was a generation ago so that may have changed.
i know the build quality of a nikon camera leaves nothing behind, mine has even survived a quick dodge into seawater(dodging the surfer i was photographing), took out the battery and sent it to the cleaners and it still functions perfectly.
odd thing is i have 6 decent analogue canon lenses so ii could have used ann adapter had i chosen canon.
