The Rebel is a MUCH, MUCH better camera than the Sigma will be. With 35mm, the only thing that affects the quality of the photos is the film itself, the lens, and the skill of the photographer, the camera body doesn't mean much.
Keep the Canon, and if you're looking to spend money, get some lenses for it. With the Canon stuff, you'll be able to upgrade to a better body or a digital, and keep all your lenses, with the Sigma, you'll be stuck.
