For my money, UPS rules.
But if you're an NFL running back, you can't do much better this early in the season than being voted FedEx Ground NFL Player of the week as LeSean McCoy was.
McCoy beat out Ray Rice of the Ravens and Ben Tate of the Texans to take the honor that is important in getting a guy noticed. McCoy, who rushed for 122 yards and scored two touchdowns to beat the Rams in the opener, might have been in the Pro Bowl rather than a first alternate had he nailed a couple of these.
Now, as far as UPS my personal experiences with them are excellent. They got a replacement smart phone to me in 12 hours via Asurion service, which also is amazing (highly recommended for smart phone owners). Almost as uplifting is no one had to sign for the phone unlike another service that always seem to deliver when I'm at work.
