Depends on what you want. Pilots will complain no matter where they go because with this large of crowd you will always have a few that got in for different reasons then realize they aren't too happy.
The two biggest drawbacks about RAH are A) You can't bid for any flights while on reserve even though the contract states it. The company interprets it another way. B) The best reason to pick a company, domicile IMHO, might make RAH an issue as they are famous for picking up and moving a base in no time. C) Joe Cespedes<--wanting to move higher up and doing all he can to get there it seems.
The good things are our CEO who actually cares, a close pilot group that communicates well, good work rules, expansion, good future outlook.
As with all companies they have their pros and cons. As far as regionals go currently you can't go wrong with either. The rumors about Xjet's future has some worried however I would have picked them over RAH since I'm from Tx.
