This "debate" really doesn't hold the same controversy or intensity as it once does. In the past it was bad dubbing vs. I can't read the damn subtitles in time. Now the dubbing has improved vastly in my opinion, not only the timing but the voice acting itself. While the Japanese still pulls the "doll-ish" voices more convincingly, the American voice actors can do it too now.
To me it really doesn't matter. It all depends on which version I watch first.
