I dunno what's cheaper really, and I doubt theres much of a difference between your options.
However, Fed Ex gives me better service. I'd rather pay a little more for it (I'm sure the Fed Ex option you listed is slightly more expensive).
Whenever something is delivered to me by Fed Ex, the person waits patiently for me to come down and get my package, seems very pleasant. The UPS person just throws whatever it may be onto my porch and expects me to magically know when to get it.
