The Sport is primarily intended as the "budget" model. The stainless steel model is the most "personal" and is offered with the greatest selection of bands. Of course, you can always purchase a leather band to go with your Sport, though if you get the Classic, Modern, or Milanese bands the steel might "clash" with the aluminum. The Link band costs more than the Sport itself, so my guess is that most people who want that would be willing to pay the extra to get the stainless steel Watch in the first place.
