USPS always delivers my packages. When I see USPS I know I'm going to get the item on time (along with 600 outdated emails regarding the tracking, but I digress). I'm in 11201. (This does not apply with packages shipped internationally. They will claim to deliver it, ignore your redelivery requests and signature releases, and then whine at you incessantly when you go to the post office to get the package. But you do get the package at the post office, so that's nice.)

UPS also does a great job. I don't know how they break into my building, but they do. Once in a while the normal delivery person takes the day off, and you get the door tag. Fill out the form online and the package appears tomorrow. Not perfect but reasonable.

FedEx is awful. FedEx means I'm not going to get the package unless I happen to be at home and they happen to actually ring my doorbell.

DHL is also awful (the delivery mechanism of choice from amazon.co.jp to the US). I order a $10 magazine and they won't just leave the package at the door. In fact, they call me to see if I'm at home, say things like "oh, you didn't answer before, I'm not on the way there anymore so I can't deliver it" and other such bullshit.

Finally there are the taskrabbit-like shipping services, A-1, Lasership, etc. If you see one of those you aren't going to get your package. Just re-order it and hope you don't lose the lottery again. They can't even successfully deliver to commercial addresses with dedicated courier receiving and fully-staffed mail rooms.
