Despite all the threads on the subject it all boils down to you. Once you have made a decision about the value of a mile you've a simple arithmetical calculation to find if csh back is worth more to you than are points or miles. Generally the credit card companies price their products so it will be financially even for them. Because they buy points wholesale generally cash back will be a better deal than will points. Generally. But specifics vary greatly. Thus a generalization does not reflect the choice you need to make. So, "your mileage may vary". I personally use some of both, depending on specific promotions to make the tradeoff for how I use them.

So, I know this answers no questions, just raises a couple of issues. Look at the threads and you decide.
