FYI Both airlines service the places I fly to so there's no issue there...

DL has devalued its miles with the 3-tier structure. That being said, it is far easier to earn miles on DL (they constantly do 30-50% bonuses, etc).
In the end, the smart thing to do is to keep them in SPG account until you actually need to *use* them, and then transfer to whoever has availability.
