Being a leisure traveler whose main point earning is from credit cards, I rank them as:

1. Club Carlson if you have the visa for the BOGO award benefit and annual bonus.
2. Priority Club for the annual free night, 10% refund on awards and PLT status.
3. SPG for good transfer rates to airlines if you can't find a hotel you want.
4. Choice for cheap Europe awards 8000-10000 a night.
5. Wyndham only if there is a promo but I transfer straight to an airline.

I don't really use the other chains because in most cases I can find a CC or PC hotel where I am going (outside of my birding -eco-lodges which are VERY remote)!
