It depends on so many things. What are your goals? Do you want to move on to FedEX or UPS. Or move on to Delta or UA? Do you want to do long extended rotations and enjoy your long extended moments of time off? Or do you want to have a few days off here and there with a bunch of 3-4 day trips? Probably the same amount of night flying at both operations. 25-30% of our lines are WOCL or have WOCL flying. 737 or widebody? International or never cross the Atlantic?

You're really the only person who can answer your question. If you have specific questions about AS I'll do my best to answer them.
