Judging the strength of users by the effects their spells have is complicated; Pan is already dead, you cant't kill him. Besides that, Emma's magic also only pushed Cruella, would you say Emma's weaker than Cruella? It probably wasn't even her intention to kill him.

You're ignoring skill level. Power level is what a person is capable of doing in their best, most well-trained state. Emma and Regina are quite mediocre at magic, because of their low skill level. This needs to be taken into account. By your logic, Emma's one of the least powerful magic users.

We have canon confirmation for Emma's power level. Her magic is true love, and true love is the most powerful magic of all.

Rumpel dominated Emma with relative ease in 5x11. I believe he was speaking the truth about his spike in power level, but there's no way we can canonically assert that.

I'm not taking gods into account since I believe there's an entirely different parameter for them than for other magic users. I like to believe Gods are extremely powerful on their territory/sphere of control, but not much outside of it. Poseidon can't do much on the Underworld, and Hades probably can't control the seas. But this is purely headcanon, so it can't be taken into account
