Best cash back credit card for big spenders

[Adam Craig]

I have done some research on this topic and it appears Alliant offers the best cash back card which was something like 3% in year 1 and 2% lifetime.

I called them today and was not aware this could not be used as a business card card only on the consumer side.

Between my 2 business we run just shy of a million through Chase business cards each year which we get about 1% back on. Is anyone using anything better? An extra percent would really add up over time.
