Agreed. The blanks are more than adequate for most cars out there. One major issue is the drilled rotors have a bad tendency to crack. To me they're more of show-off items than performance. They don't offer any cooling benefits (its a common misconception that the holes let air travel through them and cool the rotor). They are said to offer a little more initial grab, but if you're looking for true performance that's really the exact opposite of what you want.
The only decent benefit about them, to me, is that if water gets on your brakes the holes do allow the water to get out faster so that you don't have that initial braking loss when they do get wet. But to me the detriments outweigh the benefits.
