Well, in Tucson you are looking at 24/7 coverage. Days, nights and swings 5days a week minimum of 8 hours a day rotating into and out of weekends or at least one weekend day off. The QOL is nice... if you like the desert. Homes in the suburbs are affordable for a GS11, Tucson proper is expensive. The mission pace is high and you stay busy, more so during periods of high illegal immigration.
Once trained up you can probably count on flying as much as you wish to insert yourself into the schedule especially if you are an A-Star driver. You can almost always fly more than assigned if you want to.
As far as leadership goes it is unlikely they are going to invite you over for beer and brats on the weekend. They are fair and by the book. People grouse about the leadership just like they do at any job. Mandatory retirement is 57 so if you don't like them they certainly won't be around forever.
Re the other branches you mentioned I don't have any first hand info.
