Is Reconciliation the most powerful sacrament for Catholics?

Baptism is the gateway to all other sacraments and it forgives all sins, but it can only be performed once in a lifetime. The Eucharist is the source and summit of Catholic faith, but only forgives venial sins and one must first be under a state of grace to receive it. On the other hand, the sacrament of Reconciliation forgives all confessed mortal and venial sins and can be repeated as often as necessary. Does this make it the most powerful (if not the most important) sacrament for Catholics?
