Sourcing best small business banking?

Can anyone help me find where to get independent advice on the best small business banking options? There are so many banks I find it difficult to compare and contrast them. I'm interested particularly, but not exclusively, in small business credit cards and who offers the best rates and deals on them.I want the banking to be accessible online too.

Every bank of course will tell you they are the best choice. However, I'd prefer to hear that either from the lips of someone that's impartial and not earning a commission for every referral they get for the bank, or be able to compare them easily myself.

Any ideas would be appreciated on how to find the most cost effective small business banking out there. Thanks!
