Is crushed ice or block ice better for keeping foods fresh in a cooler?

Crushed ice will cool down food faster due to the larger amount of surface area that comes in contact with the food. It also can help keep the food completely covered during transit since it is less likely to move around.

However, crushed ice will melt faster due to it's larger surface area. This makes block ice better for food that is going to be in a cooler for long periods of time or is going to be sitting open on a hot day.
