I congratulate you for doing your homework. You need to ask yourself this question: "if I do get stuck at this place for the rest of my career, is this a good place to be?". You do not know what the future will hold and you do not want to start over at first year pay. Pick the place that offers the best QOL today (it may change in the future, but without a crystal ball, you have to go with what you see today). My advice is Sky West, but you need to decide.
