While I haven't tried the EdgePro, I've been using the Spyderco for the last two years with excellent results.
Unfortunately, I'm a complete oaf when it comes to sharpening a blade with a stone (and really jealous of those who can!), I seem to be able to bring the blade straight down on the Spderco, and the resulting blade pops hair off my arm. (I have a tattoo of a pinup girl on my left forearm, and she appreciates the shave!!
The Spyderco's incredible when it comes to serrated blades, too!
