J.K Rowling was mor mature than Stephanie Meyer do you agree?

I think that J.K. was much more mature about her characters because she was able to let them go for a good story.I think that Meyer on the other hand ruined the Series by making a "and the all lived happily ever after" book.(IMO) Rowling's books were much more enjoyable because it had that special kind of love in it that made the book so emotional and special.What are your opinions?
