This is not the way I read such questions. I think people are asking what's the best card for me?, but are not providing sufficient detail for an intelligent analysis with the result that formulaic responses are posted. Many similar threads are also started in MilesBuzz, and Flyertalk evidently does not have a practice of moving them here where members might read and learn from the parallel inquiries.

I think the other sources of degredation that you mentioned will be resolved now that we have active moderators ^ .

In another section you mentioned that your wallet containing ten cards had been stolen. I think that would be relevant to this topic, because it illustrates one of the tradeoffs when "optimizing" by using multiple cards.
