There's nothing wrong with any of the Miyazaki dubs, if you ask me. I love watching films in their intended language because you usually get a more honest translation (especially with Japanese, as I'm sure you know, because it's so nuanced) but I've never bee bothered by sitting in front of the TV and watching them on Disney (except when they cut stuff out and have 50 billion commercials).

I love Run Lola Run and of course, Amelie and Let the Right One In.
