Nick, part of my job for the last 23+ years has been shipping/receiving. We use UPS, FedEx and DHL. Each has their strengths, just as each has their weaknesses. Well over 80% of our packages are shipped with DHL.

Another part of my job is to field the customer service calls and we get over three times the complaints about UPS deliveries than from the other two companies combined.

Our package volume varies wildly, but we can ship as many as 25-30 packages a day, so I feel I have an pretty fair idea of how the shipping companies work.
