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

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

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

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

Try watching the dub. But they are both good!

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

Honestly I think the 日本漫画 is so much better then the Anime...Its more..complete.

Both, if 你 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
