Oh, I wish i had more time and money to spend on manga! You all got such great suggestions! I wish i could start read Nana. I have the two first volumes. I don't even remember if i ever started reading them :S And I sooo wish to re-read Chobits!! 

I am currently reading Excel saga, I'd say it's one of my favorites.

My all-time favorite manga has to be Air Gear. I think it's great.

I think some of my top favorites has to be Tetragrammton Labrynth, Alice 9th and Princess Resurrection ^_^

My favorites:
Black butler, godchild, alice in the country of hearts, from far away, vampire knights, goth cage, maru peri, yostuba, bleach, one piece, dead man wonderland, red river, parasyte, fairy cube. lots more though that I can't think of.

THESE ARE MANGAS I LOVE!!

I have read a BUNCH of mangas (more than I watch anime XP) But my Top 6 would be

 

1: GAKUEN ALICE/Alice Academy (In LOVE with this manga XDD)

2: Kamichama Karin Chu

3: Cardcaptor Sakura

4: Beauty Pop (OMG I fell in love with this one)

5: Absolute Boyfriend

6: Kitchen Princess

Naruto is a win.

 

Tsubasa: Resevoir Chronicles

Kuroshitsuji (Black Butler)

Bleach

NOT One Piece (which became several pieces after we got my friend's brother to run over a OP graphic novel I got)

Dragon Eye
