Is Anos voldigoad really badly written as most people say it is?

talking about light novel anos btw, not the anime one, because we can agree that anime anos is a tanjiro victim in writing, but I can’t help but wonder if he’s really that badly written, because I usually see alot of people who made edits slander Anos for being badly written. So for those who read the light novel, pls tell me hows he’s writing is like and how would you rate it, and is he really a fodder in writing and just only powerful?

ofc I don’t expect him to be really good in writing To the point he competes with good written characters like Eren (Attack On Titan), Thorfinn (Vinland Saga) or Guts (Berserk) cuz at that point they kinda fodderize him in writing lol
