They can do either just as effectively. Fans move air by creating pressure differentials. The diffreential pressure between the intake and the ouput of the fan causes air to move to the area of lower pressure. It has nothing to do with whether the fan is "sucking" or "blowing".
But,
generally, there is a larger "dead spot", created from the motor blocking air flow, on the exhaust side, and a smaller "dead spot" on the intake side.
