The loss rate for UPS is about 25% here (DC) and their support is in name only. They won’t even let you file a complaint for (IIRC) a week after the alleged delivery date because they know how often that’s completely fictitious.
The USPS is generally rock-solid, although during the pandemic I’ve had a couple of packages show up the morning after the stated date due to the carriers being slammed (described as like Christmas but without the temporary staff).
Amazon appears to track this: after a few lost packages they never use UPS for us. They use their carriers and USPS for all sizes so I’m assuming there’s some careful price arbitrage going on.
