Points have no set value. I only look for offers in a denomination we can all agree on the value of: dollars.
If you fly a lot, and know the value of points based on air fares, then I hear you can do well. As an infrequent flyer, I'm not there yet.
I had a credit card (PenFed) try to get me to change from a direct dollar rewards system to a "points" system. I suspect it went something like this: A third-party points management company sold PenFed managers on the idea of off-loading the whole program to them. I assume it saved PenFed money, and made money for the third party. I know their splashy ad campaign to try to sell customers on this program wasn't cheap.
I didn't see how it could benefit me. And I doubt it took any significant effort on the part of PenFed to run a batch job every month to calculate and transfer the rewards amounts. The whole thing was most likely just a money grab.
For my part, I called them to complain and they offered to let me keep my cash rewards, but for only one category. I chose 5% on gas. I have not used the card for anything else since. I pay for almost everything on a different, cash-back card. So the change didn't really benefit them in my case.
Maybe for their target audience it was a success. It seems they cater to a lot of young people in the military or public service who aren't financially very savvy. Shiny prizes to win using points might have an appeal to that demographic. I'd rather pick my own prizes with cash, thank you.
