The more people in one station you have, the more personalities you have. Suckups, cut-throats and quiet ones will be in every station. It'll matter more on the route and manager you have.
Hindsight being 20/20, I would have stayed in my 2nd station. Rural station, extended/ODA/out-of-town (whichever you call it). You go out in the boonies where, if you see another FedEx truck....they are either lost, looking for you (good luck on that one) or from a neighboring station. 300-350 miles and 45-50 stops.....I even used 1 little trick on my check ride to keep my manager from ever coming out with me again.
If you don't mind driving a lot (and some places it is a LOT), go rural.
