I’ve not watched shows that you mentioned yet so this might be a little out of left field. But anyway here’s some top anime i’d recommend:
Beautiful world that gets bigger and bigger, loved watching the main character train up to a crazy level of power. Your idea of that character will change over the time you’re watching, the writer does a good job at putting us in the shoes of his friends who also watch him grow.
This one is if you’re looking for the type of character development that you’d find in a war movie, Innocent characters learn the gruesome horrors of their life and lose their innocence. The story of the world is well built and the lore is deep. Be warned, it pretty depressive to watch, i kinda lost hope with the characters while watching it does a good job at pulling you into the characters mindset.
Others to consider (i.e. anime starter kit): My Hero Academia | Neon Genesis Evangelion | Fullmetal Alchemist: Brotherhood | Tokyo Ghoul | Sword Art Online (S1) | Does Avatar the last airbender count?
Drum island ends with Season 3 out of 21 (so far) | so episode 92 | arc 5 of saga 2, still very early in the show. Curious to see what Chopper looks like in live action.
