There is a lot of things to take into consideration when choosing a regional. But if quality of life is big for you, you should probably go with Skywest.
Right now, QOL at Envoy is terrible, it's sustainable if you live on base (which is your case) but not great.. More and more people bid reserve because the lines are so bad.. And reserve is not good either. They have awful reserve rules.
I'm not saying it will never change, but the facts right now are what I just said.
On the bright side, Envoy has a flow, and you'd make more money than at Skywest..
Good luck!
