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

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

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

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

Try watching the dub. But they are both good!

You should watch the dubbed version, but you could also watch the subbed version.

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

Both, if you 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
