I hate em both.
Figured I'd try FedEx ground. Shipped 20 packages in one week (8 pound aluminum parts I had custom cut, lathed, etc). 14 folks email saying their packages are mauled but the contents are fine. One is damaged and dinged up really bad. These items were well packed, bubblewrap and such.
UPS wanted $17 to ship each. FedEx Ground $9.85. I knew it was too good to be true. (Also, UPS had a $1 fuel surcharge, as I recall it)
Someone mentioned DHL or even the post office. You find me a postal employee who is HAPPY to see 10 boxes arrive at their counter and I'm there. At my post office, if you have 2 envelopes, the silent grimacing begins.
