One of the cookie cans has weights around the edge while the other has weights concentrated in the center. The one with weights around the edge has a higher moment of inertia and is therefore more resistant to spinning/rotating. The cookie can with the weights in the center has a lower moment of inertia and is therefore able to spin faster and win the race.
