Business Credit Cards - Best Available for Points?

Hi Guys,

Just before I do all the research and post it on here I thought I would check if anyone had already done the work.

I am looking for both a non-amex and an amex credit card that gives the best points without an annual fee (at least for first year) for a BUSINESS card (plenty of posts out there about personal cards but they're no good to a business).

I have suppliers that take amex and some that don't so I need both. It has to have uncapped points earning (some only offer points on first $10k of purchases). None of my purchases are international.

If you can let me know what you use and why that would be great.

Thanks!
