I'd have to agree with Digital Eon here. Wrong phrasing I guess.
Anyways, I highly recommend the epic masterpiece Lone Wolf and Cub. It might seem really old school at first but it'll blow you away as the story progresses. How come no one's recommending it, btw?
I'm also into Piano no Mori at the moment. It's seinen but the lead characters are kids which makes things refreshingly less complicated. Current scans are getting more and more interesting.
If you want futuristic sci-fi in a contemplative setting, go for the highly underrated 2001 Nights. The mostly one-shot stories are interwoven into a masterfully planned whole towards the end. The drawings aren't conventional manga style but the stories will grow on you after a while (I got hooked on the second story).
For more old school goodies, Ode to Kirihito is the way to go by the Father of Manga/Anime Osamu Tezuka. I don't think it available on-line though so you'd have to buy it in your nearest bookstore. At only one volume, it's very compact and very much worth your money.
AND if you're into shoujo, I know of a couple of titles that really stand out.
Also, anything by INOUE Takehiko is highly recommended.
PS: Eternal Sabbath is a bit creepy.
PPS: Aaah. Yotsuba&!. The ever-present recommendation.
But once you conquer the world, then comes the hard part.
What kind of world would you create?
