Well, there's the obvious difference, that the money stays in your account for longer with a credit card.
There are legal differences, too: credit cards are regulated by the Consumer Credit Act, which makes the card issuer jointly liable in many cases. So, for example, if you order a product with a credit card, and the retailer goes bust before supplying it, the credit card issuer is also liable.
