If you only speak English, then all of them.
Watching anime with Japanese audio along with English subtitles is just insane to me and I never understood the argument that some anime are better when subtitled…something about how the Japanese voice acting is better than the English voice actors. There is also the argument that you can watch an anime sooner if you watch it subtitled. Even if one voice is better than the other, why not watch the show in the only language you know how to speak? In rewards to having to wait, I feel like waiting to watch the English dub is definitely worth it.
