tool consideration

i am working on a project to revive some old tool boxes i found at a flea market and replace the newer style plastic tool cases that sears sells now.

so i went to Harbor freight and found some socket organizers that fit on the bottom level of the metal box but as i was transfering tools from the plastic case to the organizer for the metal box i noticed something.

some of these newer tool kits that sears sells come with either 6 point or 12 point sockets.

so my question out of that is:

if your on the side of the road with a small tool box which would you rather have .....a set of 6 points or a set of 12 points

does anyone know the advantages of each one and which one has a higher probability of being used more?
