Ok so I know that this is controversial, but if I recommend One Piece to a new person I recommend the live action. I know it has its flaws, BUT, it cleans up the pacing issues that I had in the early series. It honestly feel way more accessible than the daunting +1000 episodes, that’s not a binge watch, that’s a depressive episode.
Spider is one of my all time favorites. I loved the LN, the world building was fantastic. The way the author laid out the mysteries of the world and the dynamics was perfection. Also, it’s a isekai that forces its characters to actually deal with living in another world. It’s not a throwaway plot point that explains why they’re so much better, smarter, ect than the locals.
