To my knowledge Hilton is the only chain to offer both an American Express and a VISA affinity card. Marriott, Hyatt and Intercontinental Hotel Group are all tied to Chase (VISA). I am not up to date on Marriott's program, but I know there is more than one version of the card, and the program seems competitive with the other multi-national chains. The Hyatt card is not yet available. The IHG card is weak, aside from the signup bonus and spending at the hotels.

Some other cards issued by Chase earn points which can be transferred to a subset of their airline and hotel affinity partners. For example, Chase heavily advertises the Sapphire VISA, but they are coy about the transfer options which are two airlines (BA, CO) and two hotel chains (IHG, Marriott) mentioned here:

The smaller hotel chains tend to offer cards with no annual fee, as mentioned in the thread linked in my previous message. I suggest the place to start is thinking about the type of hotels where you tend to stay, rather than the credit card. A free night in an unsatisfactory room is no bargain.
