The best and most well-known example I can think of is Death Note... any suggestions for manga that isn't just running for the sake of itself, but is a complete, well-crafted work of literature/art?
There's no comercial manga that runs for the sake of itself, all of them want to sell; Death Note in specific seemed a furious and very well executed plan to do a great non mainstream shonen manga (and if you loved Death Note and are deep into the manga world theres almost no chance Bakkuman will be unpleasant for you).
Anyway, seems what you are looking is "Seinen" mangas, here are some amazing ones in no particular order:
- shigurui (martial arts)
- historie (historical)
- last inning (sports)
- neighbor no 13 (horror)
- the lucifer and biscuit hammer (adventure)
- uzumaki (horror)
- furi kuri flcl (??????)
- pluto (mysteri, best Urasawa work IMO)
- takemitsu zamurai (martial arts)
- drifters (fantasy)
- vinland saga (historical)
- vagabond (martial arts)
- all rounder meguru (martial arts)
- piano no mori (slice of life)
- Shingeki no Kyojin (fantasy)
- Nigiri Supahero (comedy)
- Hi no Tori (si-fi?)
- Homunculus (psicological)
Each and every one of those is a fantastic, well written manga. I can give you tens more btw, and will if you are interested in some specific type of manga.
Edit: The most artsy of those? Depends on your tastes and how keen your manga art sense is developed. For starters i would go with Vagabond and Homunculus, even if you are not into manga its impossible not to appreciate its content, writing style and art; but for me FLCL and Zamurai have even superior art for each picture it's just perfect to express what the panel is showing.
