"One Piece" gives us more joy (hilarious) and emotion (more emphasis on friendship and joy in realizing dreams), while "Naruto" gives us more emotion (including friendship, love and affection, and the complex relationship between good and evil) and courage (courage to break the shackles of fate, more emphasis on the courage of the protagonist Uzumaki about dreams than dreams, and the play only pays attention to the first generation. Uchiha Shisui, Naruto, and so on. Not everyone and their dreams are for "calming the war" and "maintaining peace".
So young people prefer One Piece (of course, this is not absolute), and adults prefer Naruto (of course, this is not absolute). One piece has optimism, openness (straightforward party), friendship (attaching importance to friendship), worship, blood and emotion (sense of joy), which we can have. As for Naruto, this work is closer to reality and exposes darkness, just like a song by Taiwan Province singer Jay Chou-fireworks are easy to be cold, and there is a feeling that "fireworks are easy to be cold and people are easy to be separated". Light and darkness are like Senju Hashirama and Uchihiro Shoko Asahara, Jiraiya and orochimaru, Hatake Kakashi and Uchiha Obito, Naruto Usamu and Sasuke Uchiha ... People are unpredictable, bad people are not necessarily bad, and good people are not necessarily good. Naruto pays more attention to the way of the world, such as friendship (people who don't know how to cherish their companions are even worse than waste) and love (as Nishida does to Naruto, it is invisible and intangible, but it will be found in later days), and family (for the future of Mu Ye Village, Uchiha Itachi, a native of Neichibo, sacrificed, but he felt sorry for his younger brother: for the future of Mu Ye Village, Namikaze Minato and Uzumaki Kushina, he and his children's husband and wife were all sacrificed. The plot is complex and fascinating. So relatively speaking, Naruto is not as "easy to understand" as One Piece, but it is closer to reality than One Piece. In fact, both Naruto and One Piece have their attractions, which is why mature and sentimental people like to watch Naruto, and those who are straightforward and sunny like to watch One Piece.
