American Express Membership Rewards - Business Gold or Platinum?

My company is need of a good Business Card that offers best points/miles possible. Any help would be appreciated.

Welcome to Flyertalk. You certainly do not want American Express Business Platinum if your primary interest is rewards rather than benefits. Beyond that it's impossible to give you much guidance because you have not provided any details. How many cardholders? (Some provide free additional cards, some do not.) What level of annual spending: $20,000, $50,000, $1000,000, $1,000,000 ? (Some cards have limits on rewards). What types of rewards do you prefer? (Some cards offer rewards on a wider range of airlines than others. For example, American Express Membership Rewards is nearly useless for awards American, Northwest, United or US Air, but American Express has other programs that work well with all of those, except United.)
