Hindu is complex and has some variability depending on the flavor. Some are left up to the individual to determine based on their perceptions.

The supreme being is genderless, the other aspects are more masculine or more feminine and some are androgenous or both. Feminine energy is the most powerful at creation and masculine is the most powerful at destruction. The gods are just a reflection of an aspect of the supreme genderless Brahman, where their characteristics favor a given gender and that is expressed in their visage. They also use names that convey a symbolism.

So no gender is the most powerful in Hindu, but different forms of gender expression have more power in an aspect of power.
