Driven pile should have more strength.

The load carrying capacity of bored cast in situ pile will be much smaller than that of a driven pile in sand. The angle of shearing resistance of the soil is reduced by 30, to account for the loosening of the sand due to the drilling of the hole.

Loose sand will get compacted by means of pile driving. So the strength generated in case of driven pile will be more in case of piling in sand deposit.
