I prefer AA
From the posts so far it looks like the general opinion is that AA is a better choice and I concur. Being a DL PM every year for the last 13-14 years and also an AA EXP I find awards availability in premium Classes to some of my destinations better with AA than with DL. The free Crown Room membership (and the free drinks) for DL PM is an added benefit as others have pointed out but in my case I already have a lifetime membership in the Crown Room. Most of my travel is international; so I get admitted anyway to AA's AC and FL (ORD, LHR, BOS, LAX).
If you are a compulsive mileage tracker needing immediate posting then you'll find that the DL miles are posted in your account by the time you land. With AA it takes a few days.
My vote 60% AA, 40% DL
