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

I would say, if tu have time, and tu are really into this show, watch both, and I can tell tu either way tu 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 tu can understand better o version tu prefer.

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

Try watching the dub. But they are both good!

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

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

Both, if tu 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
