Zelena is quite powerful and still more powerful than Regina. (Regina only stunned her, not an actual overwhelming defeat since Zelena could have killed her a hundred times if she didn't need her heart or was always monologuing.

I think it goes like this in terms of Dark Magic:

Dark One >> Apprentice >> Zelena >> Regina = Maleficent = Cora.

I think it's also because Zelena is unhindered. Rumple described magic like something boosted by dark emotions and subdued by good ones. Zelena is not like that, in that she is pretty much a gushing pipe of dark emotions and nothing to hinder that. That's why her magic is continually strong.I think that Zelena might have been a tad bit more powerful than Regina and Cora, but unlike them she's a wildfire, while they are rather tame.

In terms of dark magic users, it depends. Mal seems to be a somewhat mediocre powered sorceress with a limited range of spells.

Zelena's dark magic is much more powerful than Regina's dark magic now since she has some liught magic (which she never really taps into). Zelena would be able to defeat Maleficent, like Regina waas able to, just neither of them shown what they can do against a dragon.
