Open Question: Best way to store food while backcountry camping?

For a 6 night back country hiking trip, in Killarney ON, with 3-4 guys, is it more efficient to take a food barrel with harness or for everyone to put their food in an airtight stuff sack and carry it themselves. Obviously both containers would have to be hung at night to avoid bears and other animals.
