Easy. CAL.
I've heard nothing good about the morale at NWA. CAL has it's issues, but who doesn't, yet morale is better there. NWA is still under a concessionary contract. I can tell you, that's something to think about. Working conditions go to hell in those circumstances. I don't know the terms of Compass and NWA agreement, but those can always changes, just as the flowthrough can. If you take the Compass upgrade, then you're stuck. It's harder to leave.
Oh, if you're not married, don't!
