Spirited Away didn't make the top 10, it was ranked 11th. Though calling it the best Miyazaki shows how ignorant they are (not that it is not a good candidate for his best but it only shows that they don't know his earlier movies ).
It's not because you know all of his movies, that you can't think that his most famous film is actually also his best. You seem like a die hard hipster with your reaction. They don't have to 'show' that they watched his other movies by rating one of them higher than Spirited Away. That's just plain ridiculous.
