Doubt
Elfen Lied
Black Lagoon
Jiraishin
Battle Royale
Vagabond
Monster
Berserk
Gantz
Basilisk

Common sense is not so common...

I only have my top 5.... >.>

1. Zetman (I freakin' LOVE Zetman, amazingly dark plot)
2. The Breaker (NW too, but the prequel is just too good.)
3. To Love-Ru Darkness (Kotegawa Yui FTW, nuff said)
4. Kiss x Sis (No need to comment)
5. Onani Master Kurosawa (Anyone who's read it, will know what's up)

I don't see Shigurui in any list. It's listed as Shounen here, but it's definitively Seinen. And what about Hokuto no Ken it has to be seinen i think...

Anyway my favorite is Koroshiya Ichi, no doubt about it 😛

PS: Ciguatera and Onani Master Kurosawa are awesome mangas as well.

23. Akumetsu almost forgot that

previously in the favourite list but not anymore: (I still like them though)
Vinland Saga
Wolf Guy - Ookami no Monshou

Man is more ape than many of the apes.

the best seinen is, without a doubt, Eden: It's an endless world!...it has everything i ever wished for in a story; politics, concrete science, realistic relationships and interactions between characters, characters weren't either "black" or "white", amazing psychology and insight into the characters' personalities and finally, the mangaka obviously did tons of research, all references to different religions and cultures were 100% accurate

so yeah, eden is my number one seinen...there are many other good seinen manga ive read but listing them in order of preference will be really hard

I always sucked at measuring several things against each others, so pay no attention to the order. (but you could say Dorohedoro is my favourite)

-Dorohedoro
-Monster
-Vinland Saga
-Berserk
-Akumetsu
-20 and 21 Century Boys
-Kurozuka
--Homunculos
-Shin Angyo Oshi (but i think is more shonenish)
-Me and the devil Blues (it was good, they ended it way too soon)
-Onani Master Kurosawa
-Ichi the killer
-Kiseijuu
-Kimi no Knife
-Zetman
-Gunslinger Girl
-Battle Royale
-Shamo (altough lately i don't like it as much as in the beginning)
-Ubel Blatt
-Sanctuary
-Blade of the immortal
-Sky High

And many many more, but this are the ones that come to mind first, so i suppose you could call them my favourites
