Memolink has to be the worst point-based redemption program out there because it can take you years before you can earn enough of their points to redeem them for anything worthwhile and i've heard that they take their good 'ol time sending you your reward once you have redeemed it.

Also, about OnePass, I feel that it depends on which route you want to take your award on. I redeemed my Worldperks miles on Continental Micronesia a few years ago for a MNL-YAP hop and had no problems.
