Pay is about the same. Unless you're commuting to ANC for FedEx or something, go with ASA. Being on reserve for any regional sucks sacks, but like it was said before, if you can go home after a trip or don't have to rush for a callout...that's priceless.
It takes me 20 minutes to drive from my apartment to the crewroom at DFW. Takes even shorter to get back to the house.
