Anime with subtitles are that when the audio has not been altered meaning the spoken language remains in Japanese while dubbed anime overhauls the dialog, but lip sync can suck if that detail is overlooked since the source material for the lip sync animations regarding mouth movements as they are originally in Japanese. The thing is, when a character’s name begins or ends with ryu / ryo , they often struggle to correctly pronounce that in the English dub.
Subs, Japanese voice actors just have a completely different style. And I’d probably need subs for English dubs anyway (like I do for English-language live action movies/shows), because English is not my native language, so there’s barely an advantage.
