What are the 3 most popular Studio Ghibli films, and which are your 3 favourite films?

I think Spirited Away, Kiki's Delivery Service and My Neighbour Totoro are probably the most popular.

My favourites are Spirited Away, When Marnie Was There and Kiki's Delivery Service. All great films.

Is The Boy and The Heron considered a good film? I haven't seen it.
