Hello!
It is quite difficult to say... Only five blessings will be given to the five people mentioned in the stories. Ranking them will be all perspective-based opinions. Of course, since they are both offensive-type blessings, the Blessing of the Sword and The Blessing of the Mana are on par with one another. The following third will be the Blessing of Darkness since it is quite versatile with both offense and support (which I won't mention yet about its capabilities). Fourth I would say the Blessing of the Spirits since it dwells more with support-type magic, but goes hand-in-hand with offense capabilities, too. Lastly would be the Blessing of the Light, which dwells more into support-type magic but can be powerful in itself. But answering your main question, I would like to say the Blessing of the Sword is the most powerful since the bearer (Augustus) can wield both Aura and Magic, the Bearer of the Blessing of the Mana (Lysander) can only wield Magic, but from all attributes.
Forgive me if this is a long explanation, I just wanted to be as clear as possible to answer your question ^^,
