USPS may be the most secure but they have the tracking technology of the Amish! They once lost track of a registered package for 10 days on a normal next day destination. Lots of polite phone calls but no real info. Package just showed up and was left with out a signature. Fedex has twice deliver to a house down the street and there tracking does not show the destination address. I use UPS, package it well and insure with a 3rd party.
