I think to a certain extent base personalities reflect their surroundings. Where is the spouse's family? Pilots who love the outdoors often gravitate to west coast bases or DEN depending on their passions. Midwesterners like ORD & CLE, East coasters, NYC & IAD and Southerns/Texans IAH, of course. After raising the kids and saving some money living in low tax states and being able to commute to your base changes pilots' perspectives. To everything there is a season and at United for every pilot or stage of life there is a base and a fleet.
