From reading these posts, it sounds as if you would have a much better QOL at Southwest. Your job appears very stressful, and not that enjoyable. The money looks great for now, but who knows if that will last. It's so much more than money that's important, especially since you don't know for sure how it will shake out in the end. You are really young, you have decades left in this career. You keep talking like you're an old guy, with not much time left to fly! It is much less stressful to be someone with a seniority number, with schedule flexibility and choices.
Commuting is tough at most airlines (except for FedEx). But it sounds reasonable at SW, they seem to make it as palatable as possible. The reality is, if it was too onerous, you always have the choice to move to base. I know, the wife, the kids are planted...but it really is not the end of the world to move. If you can be home much more often, make a higher salary, just consider it is an option, don't write it off.
