Being a product of true love doesn't give you any special powers. Being the son of the Dark One means very little, but at least gives us the reasoning for his powers.

In terms of raw power, I think Emma's is sort of an unknown as is everyone's. From assumption of raw power, it goes:

Rumple

Fiona (Theory: A fairy/person is as powerful as their personal wand. So, when it was said that Rumple wasn't strong enough to undo Pan's spell, he suggested Fiona's wand. I don't think Fiona can do every spell in existence, but she is just as powerful as her wand appears to be.)

Dark One threshold--

Emma

Zelena/Gideon (Gideon had special circumstances, but he did create a portal on his own).
