There is no perfect shipping company. They all make their share of mistakes.
I'm sure we've all seen the video of a UPS driver chucking a flat screen TV box over a fence, and I imagine we've all seen video of the FEDEX driver doing the same thing with a boxed computer. Surely you've heard of the boxes marked FRAGILE that are delivered with tire tracks across them and the contents mashed flat; that one was USPS.
They all have their issues.
