I agree with the unrestricted donation part. My money went MSF primarily because they had a staff of more than 700 people before the earth quake struck and knew how to help the country.
For me, MSF's draw has always been their great accountability, much lower overhead and coverage that extends beyond those 50/100/200-year natural disasters.
