I am vehemently anti-dubs. I much prefer to watch the original movie, in its original language.
That said, I love the films of Hayao Miyazaki and Studio Ghibli. I've watched Nausicaa, Princess Mononoke, and Ponyo, and I'd love to watch more. And I watched the dubbed version of Ponyo, but it wasn't all that bad. But Nausicaa was the first I watched, and so probably my favourite, with Princess Mononoke close behind.
