First, I love USPS - Dad worked for the Post Office and then USPS for 40
years, including 30 years on a (very) rural route - it supported us nicely.
But ... for packages, in Santa Clara County, CA:
UPS works great for me, with only one exception in a couple of decades.
Tracking has been perfect, including emails showing delivery. And my local
delivery folks deliver to the door (that's not trivial - our house is 16
steps below street level.) Of course, many of my UPS boxes come from Sweet
Maria's, which is just across the bay. But not all.
USPS doesn't know how to track packages. I sold several hundred books (one
at a time) via USPS and about a quarter of the tracking requests never
reported delivery - and some never reported beyond my shipment. (All books
did arrive, however.) Other recent USPS shipments (receiving) have been
worse - some never report beyond the point of receiving billing/shipping
info - but the packages arrive anyway. However, some packages are left out
at the street by the mailbox - not good practice.
Here, for packages, UPS wins.
