1) Naruto doesn't have the obvious plot holes Berserk. Therefore Naruto has better writing than Geass
2) Naruto has more interesting characters. Rock Lee, etc are far better characters than Guts and co. This further indicates good writing, because the author knows how to develop likable characters. Griffith just wants to make me RAGE. Casca and Schierke are just fap material. And Guts is a Cloud copypasta.
