I asked my uncle the same question a while back(he is a pro) and he told me that he uses the rebel for all of his personal photos and about half of his pro shots. Even though he has the choice of whatever he wants, he really likes the rebel for the durability and choice of lens. Like dhoch said, the lenses are the most important aspect of the dslr. The body really depends on the way it feels in your hand and ease of use of the most important features to you. In other words, go to a camera shop and ask to play around with them all. Then decide which one feels best to you. Hope that helps.

p.s. I use an Olympus c740 point and shoot and I love it.
