Cross drilled rotors look cool, and they do "de-gas" the brake pads (as well as provide
better heat dissipation)

Unless you are racing, or towing a heavy load, cross drilled rotors will not provide a
noticable difference.  The do make more noise (like air fluttering about).

A good quality rotor would be just fine, but as mentioned, if you take the car to the
track, tow, or drive like me on a daily basis ;), then cross drilled is fine (plus as
mentioned, they look cool through wheels that show them off).

Do they wear pads quicker?  Not so much with chamfered holes, but the rotors may crack
between the drilled holes.  All drilled rotors are not created equally either, the pattern
that works best is a radial spiral, and are directional to some extent (left side, right
side).

On my race car, I use a solid rotor, I am not exceeding 1200F for it to be an issue.
Slotting is another method for de-gassing, but doesn't offer much in the way of aiding in
cooling.

I've been completely happy with standard design rotors on my 850.  Unless
you drive at near rack track conditions I think that the drilled rotors are
a solution trying to find a problem.
