My favourites I've read so far:

Akira
Nijigahara Holograph
Oyasumi Punpun
Homunculus

Gantz

Asano Inio has gotten me more into seinen. I've read Solanin and Hikari no Machi as well but didn't like them as much as Nijigahara Holograph or Oyasumi Punpun. Next seinen I read will be Ichi the Killer I think - Berserk has been on my list for ages but I'm waiting for it to finish before I start reading.

Berserk
Vagabond
KIngdom
Vinland Saga
Blade of the Immortal
Feng Shen Ji
Monster
Dorohedoro
One Punch Man
20th Century Boys

My best 10 so far (without ranking) :
Emma
Cesare
Dungeon Meshi
Monster
Otoyomegatari
Kimi wa Houkago Insomnia
Houseki no Kuni

Saint Onii-san

Damn, this is hard. I'm not really good at choosing one among others. Because I already picky from the start, usually seinen series that get high scores definitely my favorites. cough

Monster
20th Century Boys
Piano no Mori
REAL
Iryu Team Medical Dragon
Homunculus
Kurosagi Corpse Delivery Service
Saint Young Men
Record of Ragnarok
Say Hello to Black Jack
