As someone in the business for 20 years, (I don't work for UPS or Fed Ex), UPS has far better, newer equipment, pays their workers MUCH better than Fed Ex, and UPS's drivers have a significantly better safety record. I know drivers that work at both companies, they are both treated the same (like a number). The Fed Ex folks are always trying to go to UPS, never the other way around. I have no dog in the fight, but from the outside looking in, I'd say UPS/Teamsters is doing something right, and Fed Ex isn't. Some folks stay with Fed Ex long term, but it is more of a job until something better comes along for most drivers, UPS on the other hand, once folks get that job, they hang on for dear life.
