My Top5 x]
I'm only going to mention completed ones :]

1. Mugen no Juunin
2. Holyland
3. Covertly Gloriously
4. Forest of Humans
5. Shin Angyo Onshi

Unknown / Unscanlated Gems:
x. Covertly, Gloriously is really really good.
Someone needs to scanlate this and its spin-off, CG; Slumber x[ The art takes a while to get used to.
x. Forest of Humans is also super amazing.
The art is simple & unique, but you get used to it.

We translate dropped manga series that people still love and want back up. Go check our goal out: http://www.mangaupdates.com/showtopic.php?tid=39809

1. Holyland
2. Eden - It's an Endless World ( I'm suprised that nobody hasn't mentioned this Amazing manga yet? )
3. Shi ga Futari o Wakatsu Made (Until Death do us Part)
4. Sun-ken Rock
5. Berserk

It's haaaaaard to put some of the lesser known seinen on my "Best" list. Because, there isn't that many lol. I tried though, until I reached number 5, cred to me for that.

Bartender is the best. Well, I kinda like the word 'favourite' more. The rest can only be grouped together as equally good I guess...

1st
Bartender (9.9)

2nd
Space Brothers (9.5)
Vagabond (9.5)

3rd
Chobits (9)
Pluto (9)

Undecided (due to the states of being ongoing or on-hold or else...)
Otoyomegatari
Bokurano
Berserk

I haven't read enough though... probably many better than these out there.

Just a couple that come to mind in no particular order. A mix of some must reads for any seinen action fans, and a couple of eclectic ones thrown in for good measure.

Vinland saga
Berserk
Vagabond
Sun Ken Rock
Tobaku Hakairoku Kaij
Shamo
Samurai Executioner
Loan wolf and cub
Pluto
Fist of the blue sky
Zetman
Tough
Riki Oh
Sanctuary
Kingdom

All original badass stuff.

If you haven't read these, they're awesome and some of them are ones I tend to not find on many lists.

Kokou no Hito
Billy Bat
Vinland Saga
3-Gatsu no Lion
Dorohedoro
Kaiji
Historie
Ippo
Kingdom
Liar Game
Saraiya Goyou

Acony
Bokurano
Cesare
Gisele Alain
Historie
Kiseijuu
Momonchi
Otoyomegatari
Shut Hell
Vinland Saga

Also obviously everything by Urasawa Naoki, but I didn't want to flood my list with everything he's ever written.

Mugen no Juunin and Eden would probably both make the list too, once I get off my lazy butt and actually finish reading them. (Ditto for Skyhigh--I really need to get to reading all those sequels.) Shin Angyo Onshi is also a contender, though it's been a while since I've read it, so I'm not sure how it ranks in relation to the others.

xxxHoLic
Futatsu no Spica
Sekitou Elergy
Majime na Jikan
Solanin
Bokurano
Freesia
Witchcraft Works
Kidou Ryodan Hachifukujin
Teppu
Vinland Saga

________________
Elitism? If I am not elite, then who is?

1. Shin Angyo Onshi
2. Vinland Saga
3. Kingdom
4. Blood and Steel
5. Ubel Blatt
6. City of Dead Sorcerer
7. Zetman
8. Feng Shen Ji
9. Golden Boy
10. Shamo


Writing this done made me notice that most of the seinen manga I read is about vengeance in some way just like another one of my favorites Berserk. Another Theme that's in some of the manga Is the mc looking to find a way to define themselves as the strongest like in Vagabond.

Top 10 in no specific order:

Berserk
Vagabond
Shamo
Shigurui
Drifters/Hellsing (tie)
Ghost in the Shell
Parasyte
Violence Jack
Battle Angel Alita
Akira
