Chocobo Hot & Cold is the best. Racing might have been able to take the prize if only there weren't such small chances of getting one particular prize out of the many. The treasures that Choco digs up in Hot & Cold are also random, of course, but the difference is that Choco can score up to eight treasures in sixty seconds. One race takes about a couple minutes. Besides, the treasures that can be found on the world map using Chocographs are extremely satisfying.
