I've lived a few places and it always seems one service or the other is more reliable in that particular area. On a nationwide basis it is probable a wash for F&S. For over-night, IMO, FedEx is the leader. I live in western N. Dakota. The nearest "LFS" is 135 miles away. UPS, like every company here in the oil patch, has trouble keeping help and it shows in service. Until a couple of months ago, the ONLY place to send a parcel via UPS was their depot- No UPS stores. The depot was open for package pick up daily, M-F between the hours of 4pm & 6pm!
Thankfully, a UPS store just opened in town. They will hold a live fish shipment BUT you must first set up a shipper account- cost $10. Then each package held for you, if you do not have a mailbox account, will cost an additional $5 per box. From the manager today. Said this was national policy- prices. Be curious to find out what others find.
Bottom line is F&S/ LA always offered the consumer a CHOICE. No longer
