Is honoring one's maternal aunt equivalent in virtue and reward to honoring one's mother after the mother's passing?

The mother is the most deserving of all people of kindness and maintaining ties. The maternal aunt has a kinship tie that must be maintained, but her right does not reach the degree of the mother's right. The reason for prioritizing the mother is due to the abundance of her toil, her compassion, and her endurance of hardships during pregnancy, childbirth, breastfeeding, and upbringing.
