I suggest OEM, it's a good quality rotor for nearly all applications, especially street.

Slotted rotors are good for high performance applications, mostly for heat-related reasons and because they give the pad better bite. They eat pads faster than normal rotors though. Also noisier.

Drilled rotors - I don't know why people buy them save for 'looks'; they only appear performance oriented to people that are not knowledgeable about performance applications (where slotted is superior in all cases I'm aware).
