The slotted rotors seem to keep the surface a little "cleaner" and provide quicker bite. Other than that I really can't tell any difference other than slotted are definately noisier.
It's been awhile since I tried them. I was living in the flatlands then and driving mostly highways. I can't recall any difference in the Volvo I was driving at the time. The holes in the drilled discs I tried also rusted quickly and looked bad after the first winter. I found no difference in performance in the mountains where at times long descents can cause heat buildup. I no longer believe in the claims.
