One big advantage to slotted rotors is that the rotors are not subject to uneven wear like their cross drilled counterparts and are much harder to crack under high thermal loads.

I have had cross-drilled rotors on several cars over the years, and haven't noticed anything abnormal at all. No excessive wear. In fact, I managed to get a sweet deal online for a set of silver-arrow cross-drilled rotors for my 129 SL600, and I have about 19k on the brakes since then and have had no problems.
I had slotted rotors on my porsche for a bit, because someone got it in my head that they reduce glazing and improve performance. I replaced the pads twice in +/-20k miles because of wear/squealing. The second time, I switched over to cross-drilled brembo big reds without the slotting, and then it was back to the normal wear routine.
I suppose it could have been any number of things, including the pads I was using, and I am definitely comparing apples to oranges since it was two totally different vehicles, but I still think the slotting had something to do with it.

Actually, it all depends on your pad compound but a properly set up slotted rotor should not eat the pads.
One big advantage to slotted rotors is that the rotors are not subject to uneven wear like their cross drilled counterparts and are much harder to crack under high thermal loads.
