From an indepth Anaylze I look at powerscaling like:

Merlin: Gained immense god like power from drinking from the holy grail. Had an immense amount of knowledge.

Dark One: Any Dark one because you gain all the power and knowledge of the previous dark ones.

Blue: Mother Superior to all Fairies.

Black: Spent years learning Dark and Fairy Magic.

Zeleena(With Pendant): Born with an immense amount of magic and had the witches of Oz magic and knowledge at her disposal. Was given a pendant that amplified her power for 28+ years.

Regina: Born with powerful magic. Trained under the Dark one, trained with Maleficent and gained knowledge from Cora. Develops Light magic later on.

Cora: Trained with Rumple, stole Maleficents spell book and studied Fairy Magic at some point.

Maleficent: Highly skilled sorcereress. Spent years developing a powerful Fire Spell.

Ingrid: Born with immense powerful Ice powers. Learned some witchcraft along the way.

Elsa: Born with powerful Ice magic.

Emma: Born with powerful Light magic

With that develop your list as you please.
