Yep, Emma's power trumped Cora's and even still was a thorn in  her side when she had to remove the second protection spell without Regina. And this is the same Cora that easily extinguished Zelena's and Regina's magic and is on par with her daughters (maybe less so raw power-wise, but plenty of experience and knowledge).

Aladdin's feat of raw power keeps somethings in mind. There is raw power, but output and capacity are different. Once hasn't went into detail so that's just my headcanon. An example would be Jafar versus Amara. Amara has a stronger output of magic (her telekinesis was stronger), but they probably have the same magical capacity. I say this to lead into where I place Jafar (with Staff). Before, I thought of raw power as one thing, but it isn't. We don't have all the technical details to fill things out. like I think Rumple has the same magic output, but twice the magical battery to draw from. All this to say, I would have put Jafar and Amara high up because that's two magical powers there, but greater storage would mean that much isn't changed. Likewise with Zelena without the pendant. (Or the writers casually forget).
