I have read that drop is a better bet in terms of defending against an attack: 
packets sent to the box disappear down a black hole, and the attacker may not 
be able to ascertain the state of the victim.
In terms of cutting down network traffic with respect to msblast, drop sounds 
like the more appropriate of the two.
