Cross drilled rotors are good at dipersing heat during high speed braking which helps the rotor from possible warping over time.
slotted are meant to keep a fresh surface of the pad in contact with the rotor and avoid it from getting glazed making it harder to stop due to less friction, but in turn wears down your pads significantly faster.
im sure u already knew at least most of that but figure out what kind of driving you do the majority of the time and how often youd like to replace brake parts and the choice should be too difficult.
