IMHO makes no difference with UPS, FedEx, DHL or UPS Ground. The damages are usually during the transit, when the machines have no idea if you are shipping an Ayon in triple boxes, or a box of egg wrapped in old newspaper. Have 4 inches of sold cushion (not foam peanuts, not cheap breakable foam block) and you’d be fine.
It makes a difference with FedEx Ground as I found their local drivers absolutely don’t care and would happily drop your package from the truck to the ground when nobody is watching. Note that I see FedEx Ground out-source quite a bit of work to old-timers (who can’t even bent their back), or off-shore nationals (always in a rush). They either cannot handle weight or just don’t care.
