Subbed, but I also don't mind dubbed in most cases. Unless it's a situation like the Chinese donghua All Saint's Street where they changed the opening theme song for the Japanese dub and I prefer the original better. I have little experience with the Japanese dub* outside of that, but I kinda like the VAs better for the original dub. I know donghua is not technically anime, but I don't care.

Though, I will switch dubs to another language if I like the voice actors better. So, sub or dub is purely up to preference. Case Closed? Really wish they continued the Jimmy Kudo ENG dub so badly that if I ever became rich enough, I would buy the rights and continue that dub. BEASTARS? Sub is better, IMO. But wouldn't mind checking out the French dub for just a singular character.
