For Me it is Naruto and Samurai Deeper which I think is tha best...

My favorite mangas are actually probably Chobits and Sailor Moon. Say what you will.

id have to say that the best mangas are rurouni kenshin ,tsubasa,and love hina

Some of my current favorites are Kare Kano (Self explanatory if you've ever seen it) and Cannon God Exaxxion (What can I say? Kenichi Sonoda is just awesome.). I'd be hard pressed to name the "best" one I've read, though.

For Me it is Naruto and Samurai Deeper which I think is tha best...
Definately Naruto because I just simply love. I donm't really care if others tell me how stupid I am to like it, but definately I'm deeply touch by the stories behind each charcters' life. I'm easily touch with emotional stories so this manga really gets to me. I know exactly how hurt it is to not be acknowledge by anyone.
Also I"s because of it's superior drawings. I am truly amazed by this artist's drawings. Two thumbs up for that.
Last but not least "Mars" a manga about various aspect in life which discuss many issues in life......like insect btwn step father and daughter, love between two persons living in a totally diff world, and issue with family problems....etc. This manga is a whole different style of drawing from any of the previous style I see so far.....Truly unique style added to it.

insect btwn step father and daughterXD XD XD

Seriously, I have a lot of respect for the author of Mars, though I've only read a bunch of short stories of hers, none of the longer series. >:
I also like her drawing style, but I cannot say it looks very different from other styles I've seen lately. It goes in the same directions as a lot of shojo styles... Which hardly matters, anyway.

So, "best" manga? Impossible to say. I consider a lot of series really good, and love them, but they are often so different, it's just impossible to compare them to one another...

You see, I just cannot answer this question seriously. Stuff does come to my mind, Monster, Naru Taru, Blade of the Immortal, + Anima, Hikaru no Go, Hunter X Hunter..... o_O....... and yet, to each I'd probably know a weakness, something to complain about, that could have been better, that prevents the manga from being perfect..... ;______;

So I'll just say: Cyborg Kuro-chan!

The concept of the "Best" Manga is very subjective to personal opinion. The ones I enjoyed most are oldies

DragonQuest: Dai no Daibouken
Yawara!

I haven't been collecting any manga of late but I do buy the weekly Jump. I most look forward to (in no order):

Death Note
Eyeshield 21
Busou Renkin
Ichigo 100% (although things go WAY out of hand sometimes)

and from time to time, Prince of Tennis gets interesting.

Saiyuki, Naruto, Ragnarok and Faeries' Landing

Naruto, One Pieces, Death Note, Hikaru No Go... among all... the best is Team Medical Dragon

Slam-Dunk also... in the top 6 of mine

This thread is three fucking years old. Reviving it is pointless and stupid, especially when there's a Favorite Anime/Manga thread stuck at the top of the first page on the forum.
