I try to use UPS exclusively down here, I know my driver personally, we have each others' numbers, and he lets me know when he drops something (we live behind a security gate so they drop packages in a large job box at the gate.)
FedEx doesn't have much of a presence here at all, we never see the same driver, the closest facility is about 1.5 hours away. UPS had a warehouse that was only open about 1 hour a day that was totally useless. They closed it about a year ago so now we drop stuff at the equipment rental place which is closed on weekends.
I recently bought a long gun on my C&R and the seller prefers fedex because he's had issues with UPS. After I explain the situation here he agreed to ship UPS. I received two items from UPS right after that conversation. I ordered some mags from Checkmate, when I got the box it was soaked in diesel, there were no mags inside, just an injector pump for a Cat backhoe. The other was a long gun where the last 18" of the box was almost torn off and the bubble wrapped butt stock was sticking out the end. I called the guy back and told him to ship my C&R gun any way he felt comfortable, shipping stuff is a crap shoot and I was basing my opinion of UPS mainly on my driver, who has control over a very small percentage of anything that may or may not get to me. The seller of the C&R gun ships a lot of guns, and told me he quit using UPS because of stuff like I experienced, and he noticed that most of the issues he had with them happened when they had packages over the weekend, which makes sense and was the case on both of my recent issues with them. I have started only shipping on Mondays.
