I personally do not care for Fed Ex, they have screwed so much stuff up that I ordered I avoid them at all cost
In my opinion they are complete morons. They are 'contract workers' that way Fed Ex can work them cheap with no benefits so the people actually don't give a sh++.
UPS is Teamsters, union guys, they get good pay and benefits and it shows in their work, I have never had a single issue with them they are really good.
