I also think UPS is the best company overall for important packages... FedEx can't quite hang and DHL is a joke. UPS does cost a bit more on average, but if it saves you losing one out of 100 boxes, it's worth it. If you were shipping supplies, I'd probably use FedEx because you'd save a few bucks and the delivery date isn't as critical if it was late a day or two. In all the hundreds or thousands of "live" packages I've shipped, I've been pretty impressed overall with UPS.
