None of these are good events, the best event is lucky dice however in lucky dice you do get value but it's not focused like say in sage treasure event, for example in dice you get medium refines and seal scrolls and magatamas but it's not guaranteed that you will only get Seal scrolls and medium refines only, you might get coins or summoning scroll/potion too but the overall value of dice event is the best especially if there is masked man or minato jounin.
