What I like about FedEx is you can have your packages deverted to pick up at a FedEx office for free which many are open 24 hours but UPS charges $5.00 per package to be deverted to a UPS Store. This is convienant for people at work so the package isn't left on your doorstep of if a signature is required.
UPS is free to divert a package to a UPS facility. UPS stores not owned by UPS costs $5. I have recently had trouble registering for FedEx delivery management. They do not distinguish well between persons with the same first and last name and don't look at middle initials.
