Business is higher “ranked” (and more selective) at UF, but CS majors have one of the highest starting salaries of any major (CS is currently a hot major). Take some programing, calc, physics, chem, and business classes your first year, and then decide on your major.
You can also major in one and take a minor in the other. UF offers a minor in CS (via the College of Engineering) and (in the School of Business) a minor in Business, Entrepreneurship, Info Systems, Real Estate, Retailing and Accounting.
Either way, UF is very flexible in allowing you to switch majors in your first year or two.
Good Luck!
