Good list. There are some I don't know but I will definitely take a look at them. I read more mangas than I watch animes though. I seriously doubt you didn't watch or read Monster but if you haven't you definitely should. Takehiko Inoue's Slam Dunk(also an anime), Vagabond, Real are great mangas too.
And Mushi-shi is my favorite series. I didn't think I would meet anyone who liked it.
I used to read a lot of manga, but not so much anymore. My favorites are
Berserk,
Yokohama Kaidashi Kikou,
Vagabond (props again for your good taste),
Monster (yes, I both read
and watched it),
Akira,
Hellsing, and
X/1999.
Mushi-Shi is #2 on my list. I also recommend it to people above
Texhnolyze because
Texhnolyze is so inaccessible, while
Mushi-Shi is great for everyone. If you don't like
Mushi-Shi there's something wrong with you. Also, FWIW
Kino's Journey is the closest thing to
Mushi-Shi that I know of, so if you haven't seen it, put it high on your list (it's also only thirteen episodes).
Oh, and if you plan to get into
Texhnolyze, a few things to keep in mind. First, it's really really slow, especially near the beginning. In the first episode no one talks for the first eleven minutes -- at all -- and it also takes the show as a whole about seven or eight episodes to get going. Second, it's friggin' confusing. I've watched it five times, and I still don't "get it," or at least not all of it. It takes at least four or five episodes before you start feeling like you have a vague idea of what's going on. Third, watch the dub if you can. There is so much going on visually in this show and it's so confusing already that reading subtitles is a bummer and will probably detract from the experience (great voice acting on the English version, too). Last, try to go in with as few expectations as possible and enjoy the show for what it is, because it can be the best show you've ever seen or just seem incredibly slow, dense, and boring depending on how you approach it.
Good luck. PM me if you want to talk about any of this further.
