If cost isn't considered or I want it quick, FedEx Next Day. Otherwise, it's definitely USPS Priority with Delivery Confirmation. I've never had a problem.
Forget UPS for me - due to extremely poor service to homes, I will no longer accept any packages from UPS. If one is left at my door, UPS gets a call to come pick it up.
I don't support any businesses that ship UPS only. I've had such poor service from them in the past 2 years, I refuse for any of my money, whether indirect or direct, to go their way. I'll admit, however, they do seem to do a much better job of servicing business to business transactions.
