Cora was an incredible powerful sorcerres, it's even noticed when she was trying to gain access to Storybrooke how fearful Rumple and Regina both were of her passing through. I think compared to the dark one she is very powerful, but Rumple noted in his letter to Cora that Regina orignally thought was for her that he considered Zelena to be the most powerful, even more powerful than Cora.

And yes, I agree on some level with Eva being snobishness. It seems as if Snow White's family line has a history of ruining The Miller's (Regina/Cora's) lives, even though Snow's was indirectly, Eva's was directly towards Cora. However, Cora was a selfish woman who wanted to use royalty to gain power before her magic. So, Eva took advantage of catching Cora's hidden pregnancy in order to ensure that she would in fact marry into royalty instead of her. Kind of a 50/50.
