Let me be a lil more blunt to help in your decision and since your more pure and some of the responses border of childish. I worked here some few years now, and I came from another regional, its not the best, but its better than my previous regional, in pay, QOL (I live in base now), and flying for me at least.
Eagle is a good company also, but take in mind, RAH is moving towards much less exposure to 50 RJ's and Eagle has over 150+ 37-50 RJ's and AMR wants to sell them off soon. Those 2 factors, selling off and having 100+ of inefficient jets on their own hands to deal with now, is a perfect storm of some instability. That’s goes also with any large 50+ seat jet operator in the near future. Yes, RAH is also now paying for fuel and also has risk, no one is safe, but they can mitigate it a bit by reallocating or "right sizing" the fleet, IE E170's/145's being replaced with larger E190's Airbus and at some point Cseries.
In the end its a crap shoot, good luck
