I don't think it was ever stated that Glinda is the most powerful light magic user in Oz...? Aren't all of the witches supposed to be equal?

Zelena is stronger than Blue (well, we have to assume, since Blue never stepped in to stop her; then again, she doesn't any other time, either), but she also doesn't use light magic anymore. And the other three witches... actually haven't used any magic at all on screen? But Zelena defeated them, too... (moral of the story: light magic is not as strong as dark magic unless a main character is using it. So if you can't defeat a bad person in real life, you are someone else's guest star!)

My guess? They're roughly equal. But there's not much else we can do besides guess.
