From the way it's described in Bakuman it seems just like the manga one would have expected from the team that brought us "Death Note", compelling characters, a dark theme, and a reflection of society. A part of me wishes they had done that instead of Bakuman, although I really do enjoy it, especially the inside details on Shonen Jump, as well as some of the concept mangas introduced.
I think I would really enjoy reading Hideout Door (I'm kind of a fan of fairy tales), but Kiyoshi Knight has to be awesome. The main character is so ridiculously badass cool ("I'm fine as long as my guts don't fall out") that the series has to rock.
From the brief times that we get to see of each of the mangas, I think my favourite would be Crow, though I'd really like to see some real action scenes from it to be certain.
Actively Reading: Beelzebub, Bleach, Claymore, D.Gray-man, Fairy Tail, Naruto, Gintama, One Piece, One Punch Man, Pandora Hearts, Princess Resurrection, Shingeki no Kyoujin, Silver Spoon, Soul Eater, The World Only God Knows, Toriko, Tower of God; My Manga List
i think the best manga overall would be crow for normal shonen stuff and trap for cult stuff
BUT my personal favourite would be kiyoshi knight, because its just over the top hotbloodness.
Even though i also like the setting of Hideout Door.
The only thing i could never read is Otter, it's seems as wacky as bobobobo and i don't like these non sense mangas... i can't understand how Mashiro said it's ">jump< style"
