It's better in a different way. Madhouse outdid themselves. Whenever someone quotes a Madhouse work this one is brought up. Almost a hallmark in some ways.
It presents stuff with a vibe different to how I imagined it while reading. Very worthwhile. Would do both.
Some things would be reluctant to be adapted though. If they adapted 20th Century they should've done it way back because it'd be a show that fits best under older production value. The Trigun vibe I say. If they adapted Kokou no Hito or Vagabond I'd leave. There's not a studio that has the capabilities of doing justice with those without pulling some massive effort into making the best production in anime history or something. Something of that magnitude....I'd leave.
