actually amex are also the best for chargebacks from a merchant's perspective. they have an online interface you can log-in to and instantly see inquiries, fraud and chargebacks, and respond immediately.
they're also excellent about managing chargebacks, like when a chargeback comes through and you've already given a refund. this is so frustrating with Visa -- they'll actually still process the chargeback and ding you $20, even though you've already given the money back.
