Drilled and/or slotted rotors seem like a great idea because they would seem to dissipate heat and brake dust/debris. However their inefficiency can be found in that there is less overall surface area for the pad to contact as well as the fact that the area around the drilled holes tend to cool quicker than the rest of the rotor causing the area around the holes to crack.
An adequately vented blank rotor and a pad chosen for its intended use will yeild the desired result more-so than any other combination.
Here is a link to an awesome forum sticky pertaining to this subject:

Good reading!
