I don't think it ever said light magic was stronger than Dark Magic. The only reference that I can think of is when Snow and David met with Glinda, and that particular encounter only mentioned that it would take the strongest light magic to defeat Zelena. Which everyone thought was Emma (and still do for that matter), but Regina's light magic was strong enough to overcome Zelena. Which is why I place her ahead of Zelena in order of strength.

I think that, as Regina gains more confidence in her Good characteristics, her magic overall, and her light magic in particular, is going to continue to grow, and I do think she has the potential to be an Expert of Magic (to use Esk's heirarchy), on the order of the Apprentice.
