Apparently I get unlucky as now USPS says the package has been delayed and they don't even have an estimated delivery date, despite me being on the West Coast and my Modius shipping the morning they were announced. Still, could be worse. I ordered Magnepan LRSs in February, still waiting for them. And the Rel subwoofer I ordered has also been delayed by UPS due to "civil unrest".
Over the years, living in various locations, I've had any number of problems with the USPS and FedEx. I've always been happy with UPS, but I'm sure that for other people, they could go on about UPS problems they've had, and say that USPS or FedEx has been great for them. My understanding is that all of them have been getting hammered with well above normal package delivery levels, even surpassing pre-Christmas shipping levels.
Several years back, a FedEx driver had explained to me that FedEx express delivery services were almost like a separate entity from FedEx Home and FedEx Ground. I imagine that it depends to some degree on the pickup and delivery locations. When I lived in rural NH, they were separate. The woman who was the normal express delivery driver would drive up my long driveway and deliver items to my door. FedEx Ground would possibly leave packages by the side of the road, where they might get plowed into a snowbank, or might just leave them at the wrong house altogether. Where I live now, in a suburb of Portland ME, I have no problems with FedEx Ground. I recently received two items from Schiit via FedEx Ground and have another package on the way from them.
I've been shipping a bunch of stuff lately with UPS, and I've been very happy with them.
My USPS carrier refuses to leave packages on my porch, even prior to COVID-19, and I've come home multiple times to soaking wet packages sitting in the middle of my driveway. Yes, I've complained, numerous times and at escalating levels. Apparently USPS union employees are untouchable. I'm sure that for every douchebag carrier like mine, there are 99 good ones, but I avoid using USPS because of it. YMMV
