I agree that the stock Ford rotors are good. Mine (and the pads) lasted 50k miles. I'm working on Powerslots right now though, and they are working very well with 19k miles on them starting with new stock Ford pads. They seem to resist fade better than the stockers, although I haven't had them on the track yet. I personally don't worry about being able to turn rotors, because any time I've ever tried that they've just warped again within a few thousand miles.
I've had drilled rotors on two different cars (an SHO and an AWD DSM) and they only lasted 25k miles or so before cracks started appearing between the holes on the rotor surface. I will not be using drilled rotors again on a street car.
If you like how the car stopped before, just get some new stock rotors and call it good. If looking for a (fairly small) performance upgrade, I'd suggest slotted.
