As everyone has said, if you commute you will be miserable. I would pick a base in a city they currently run. Don't pick a place and hope it comes. From what I have heard from pilots jumping on my planes is if mia comes back it will go super senior and most likely you will not get in that base for sometime anyways and still end up commuting.
As a example for when I was thinking of Republic awhile back and hoping for the mia base I was told at best it would be 1 year that I would get it after joining.
Go where your happy and this whole regional job thing will not make you rage quit when you don't get to home after a ******** trip...
