CS by far. Business degrees don't actually teach you business, nor do they qualify you for business management jobs.

It would probably behoove you to learn about business as well if you get a CS degree; it opens up some doors and will prevent you from getting taken advantage of so much. But the way to do that is to go out and actually try to sell something (whether it's your labor, a webapp, lemonade, whatever) and make money off it. Business degrees usually function at too high a level of abstraction to be useful for any one particular business.
