Regina is clearly superior to Emma there is no question about it. Regina is more Knowledgable about magic then Emma, her Fire balls are stronger then Emma's light blast(As shown when faced off against Elsa snow Monster), Regina has a wider range of magics both light and Dark something Emma only had access to when she was the Dark one. Not to Mention Regina feats drastically outclasses Emma's. Regina was so powerful that she was able to cast a spell that even Cora couldn't get through when she enchanted the mirror. She also cast a spell on Henry to protect his heart that even Pan couldn't break through it. Not to mention she was the only one shown to be able to face off against Pan's shadow.

The only person shown to be superior to Regina is Rumple. Regina overall is clearly stronger then Zeleena as she was able to disarm Zeleena with her light magic, while Zeleena was attacking her. Regina is being understimated because we don't see her using her magic that much in the later seasons. Regina was so powerful she had the whole enchanted forest under her control. She was also able to put Sidney back in the mirror. She was also powerful enough to undo Emma Dark one spell on one of the dwarfs.
