ok this is a câu hỏi for all u Ouran High School Host Club people out there!!!!!!

I would say, if bạn have time, and bạn are really into this show, watch both, and I can tell bạn either way bạn will not be dissapointed, the Orginal ( with subtitle ) is great, and in the dubbed version, there are alot of great english voice actors voicing the Characters, as Todd Haberkorn, J. Michael Tatum and Vic Mignogna, if I name a few : )
Hope this answer helps ^^

Subbed.

Dudded is the way to go and I watch them on a site called anime freak. Dudded anime is SO much better is Subs. I really hate Subs, I don't know why It just drives me crazying watching anime with Subs.

Should the voice its in matter?
Just watch the one bạn can understand better hoặc version bạn prefer.

Dubbed i tình yêu the American voice actors they got for it. Maybe bạn should watch one episode of both and see which one bạn like better

Try watching the dub. But they are both good!

bạn should watch the dubbed version, but bạn could also watch the subbed version.

Honestly I think the manga is so much better then the Anime...Its more..complete.

Both, if bạn have the time ^^
I must say, Funimation did an excellent job with the dub. Watching the original Japanese is always a first priority in my book, but the OHSHC dub is one of the better dubs out there :3

Sub ^^.

both, but i can understand sum of those captions
