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

I would say, if あなた have time, and あなた are really into this show, watch both, and I can tell あなた either way あなた 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 アニメ freak. Dudded アニメ is SO much better is Subs. I really hate Subs, I don't know why It just drives me crazying watching アニメ with Subs.

Should the voice its in matter?
Just watch the one あなた can understand better または version あなた prefer.

Dubbed i 愛 the American voice actors they got for it. Maybe あなた should watch one episode of both and see which one あなた like better

Try watching the dub. But they are both good!

あなた should watch the dubbed version, but あなた could also watch the subbed version.

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

Both, if あなた 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
