Absolutely anything from Osamu Tezuka, while I'm currently not interested in anything else.
I'm waiting for Next World vol. 1 to arrive in the mail (already have 2 and it looks so goood.
![Sad :(](./images/smilies/icon_sad.gif)
And I haven't read my Pluto vol. 2 and 3 yet cause the rest isn't out in French yet, so I'm going as slow as possible.
For fun, I'll rate what I've read from your list, Mf_2:
MW: good storytelling but I found it to be weaker than most other Tezuka manga I've read so far cause it kind of drags in places. However I really liked some of the "intimate" moments. It's still excellent of course, cause Tezuka is just that good.
Dororo: Absolutely wonderful. Great art, strong character development, the characters are very lovable too. A real shame the series ended so fast. This is a series you pick up and can't put down, growing surprised when you've already finished a volume. After reading this, watching the movie was a real disappointment; it doesn't compare at all. And I hope you don't know the big spoiler yet, good stuff!
Pluto Vol. 1: Powerful stuff and even after already knowing the basic Astro Boy story, it feels all the more overwhelming to see the basic characters being developed to the extreme.
Phoenix: Volume 1 still remains the best manga I have ever read to this day. Of the entire Phoenix series, I thought it had the best relations between the characters. Like good fiction should do, it makes you strongly feel all sorts of emotions and not just good ones. There are times when I shouted angrily at my book. XD
As for Vol. 3, Yamato is the funniest Phoenix chapter and Space is very technically impressive.
Lost World: Very charming (The Mimio rabbit character is a highlight) and although it's quite simple, I thought it was better than the Metropolis manga. The art looks a bit flabby though.
