i have the ebc green stuff pads. i replaced my rotors and pads at the same time, from both stock (or oem) to powerslot rotors and the ebc pads. incredible increase in stopping power. a VERY noticeable difference. i really like the setup; HOWEVER, one of the reasons that i chose the ebc pads was because they really emphasize the reduction of brake dust from their pads. let me tell you that if they're not as bad as the stock pads in dust buildup, they're worse. but, if you're concerned with performance more than that, go with them.
