For me, the best quality service including tracking is FedEx head and shoulders above all others. Next, UPS--but we have a problem at least in this location because they deliver and pickup late. In one instance the driver heaved the package, a heavy coat for a daughter headed off to Ireland for a year, into the yard. The dog found it, opened it and totaled the coat! Fortunately the vendor, LLBean made good on the deal--the driver was not supposed to do that type of delivery under any circumstance. Last, and very least, USPS--tracking in name only, and delivery that makes you want to cry.
