People say drilled are weaker and will crack. Slotted has less material removed and stops glazing. Blanks have more surface area but will heat up and possibly glaze.

If I had to personally pick, I would go slotted.

You are right about the cross drilled developing cracks but that usually happens if the holes aren't chamfered.....the non chamfered rotors are much cheaper so buyer beware.
