Because of the volume of my business the difference in cash back matters a lot to me. And some cards don't give me very generous credit line so it is difficult for me to charge >$100K per month.
Regardless of the CB rate, this has to be on business CC and you can't cycle the CL. So the business charge CC is about the only "safe" way to go. And AmEx receives Level 3 codes and they can say what merchandise you can or can't buy for business purposes. Liquid or money equivalent "merchandise" is considered MS activity. If you buy or sell DVD, toys, games or clothes, it is legit business.
Also, after you set up your business, BA or any other banks should be able to open higher CL on your business CCs. I've dealt with both BA and WF small business people. They are eager to open CL for you.
