I think if you're at PSA now you'd be foolish to go to another company of the same segment of the industry. Of course, only you know what best suits your situation.
All these places are basically the same, or at the very least quite similar. The only thing that can really make your personal life nice is your QOL at whatever carrier you're at. And the one thing that drives QOL at ANY of these places is seniority.
If I had it now, I wouldn't start over at the bottom of the same type of list with different color planes. At least not on my own free will. Good luck, hopefully bigger and better things are on the horizon.
