Please read Monster, because Urasawa Naoki is the greatest contemporary mangaka.
I need to weigh in here. This post does not do Urasawa-sensei justice. The man is a sheer God, not only the greatest contemporary mangaka, but in all fields of comics/graphic novels. His writing is some of the greatest stuff to my mind, he can introduce a character for a single chapter and in that chapter you will
give a damn about that character, you will care about that character. They might never appear again, but they will have a profound effect on you, the characters they interact with and the story. The man's work is so methodical and calculating in terms of story, but just filled with so much love, heart and raw emotion. He brings me to tears with his work it's so touching at times. And all this without even mentioning his art; it looks so simple yet has fantastic detail in it, the expressions are fabulous and again give so much to the emotion. Some of his best moments in his work are simple close up panels on the reactions of a character. He tends to use "templates" for his characters, but to me that just makes them feel like familiar faces that you know from somewhere else, it gives a sense of comfort, of an instantly recognisable style. If I could create works like anyone it would be Urasawa.
So, all in all the must read manga that you must read should be
Monster,
Pluto and
20th Century Boys. Monster is my favourite and his strongest work, it's quite long and is very difficult to get a hold of all the volumes. Pluto is probably an easier introduction and quite short (that was my first taste of him). 20th Century Boys is one volume away from being finished here, there's a hugely successful movie trilogy of it which is also worth a look (things are a bit different form the manga but it's still quite good).
Other things you should read:
Azumanga Daioh,
Yotsuba&! (both by the same mangaka, both the funniest things of anything
EVER!).
Berserk (epic, bloody, dark fantasy),
Claymore (similar but with a female cast),
Bakuman (a manga about mangaka and friendship from the creators of
Death Note),
Gantz (the last volume I read featured aliens, dinosaurs and a panda, what more could you want? Always features plenty of blood and boobs). I like a bit of shojo too so would recommend things like
Hot Gimmick and
Nana.
