Noah and his family were saved from physical death.
Mary gave birth to the Son of God.
I’d say that that makes her more exceptional than Noah; not to put Noah down at all, but I don’t see the two states of holiness comparable.
I would say that both were blessed by God. Both were used by God to further his plan of redemption. Both were sinners chosen by God to do his will. I would say they were equal. Equally blessed for God’s glory.
