My own experience here locally has been that Fed Ex is far more reliable than UPS.
I have a gate across my driveway. If I don't leave it open on the day I'm expecting a delivery, the Fed Ex guy gets out of the truck and opens it. And closes it on his way out. The UPS drivers, on the other hand will either leave a "sorry we missed you" sticker or toss the package over the gate.
I found a $1k microphone I'd ordered, lying on the ground, in the rain where it had been sitting all day. It had been tossed over the fence. Thanks, UPS. Fortunately, it was well-packaged and unharmed.
Another time I had waited all day for a highly-anticipated delivery. I heard the truck pull in, but before I could get out the door he'd already turned around to leave. I literally chased him down the driveway, but he either didn't look back or was ignoring me on purpose. I ended up having to pick up my new Hammond at the UPS office.
I used to have a dog. A large Akita, he could be quite intimidating. The UPS drivers wouldn't go near him. But one day the Fed Ex guy pulled in, prepared with doggie treats in his pocket. When I arrived, the dog was sitting in the driver's seat, hoping to go for a ride. The driver, unfazed, had me sign and then gently coaxed the beast out of the truck with soft language and another treat.
I have received computer equipment that looked like it had been dropped from a great height. Think about how much force it takes to crumple a computer case. That's not an accident, that's some disgruntled UPS employee who's pissed off that other people are getting stuff and he isn't.
