I wouldn't even go with slotted. These days they simply don't offer anything over blank rotors. Actually, with blank rotors you have more surface area than slotted or drilled. Slotted rotors were made to let out the gases created by pads... pads no longer create enough, if any at all, to need slotted or drilled rotors. In a lot of cases, many pads already have a slot in them anyways that would allow anything to escape if it did happen.
One major issue with slotted rotors is that they tend to eat pads quite fast. Drilled rotors are known to crack. Another thing to think about is many very high performance race cars out there use simple blank rotors. The only benefit you might see using drilled or slotted rotors is if water gets on them. If heavy water gets on blanks you'll have a period when you first hit the brakes that they don't seem to work while drilled/slotted will get rid of the water rather quickly so that you shouldn't notice it.
In the end... with current technology as it is, drilled/slotted rotors are really for looks more than anything. They simply don't offer enough over blanks to justify their downfalls in my opinion.
