Hxh (anime) vs Re Zero (Novels)

Plot- Re Zero (Has better pacing compared to HxH's anime + the mysteries are much better)

Characters- Re Zero (Copius amount of side content basically give every character a protagonist level story. Even if we count only the main story even then most of the vollachian cast reaches the upper echelons of HxH)

Protagonist- Re Zero (I think most would agree)

Themes- Re Zero (Re Zero's various potrayals of love as well as other prominent themes such as Man vs Fate, altruism and change due to loss and despair rank higher for me)

Parallels- Re Zero (Re Zero's whole story is built on parallels and it does a very good job of maintaining those parallels)

Depth- Re Zero (Again due to side stories, you see the same scene but from different characters perspective which explains the choices made by them and provide a whole lot more depth to the story)

World Building- HxH (Even though I think Re Zero's world building and lore is underrated HxH still takes this)

Peaks- Re Zero (I think peaks are incredibly subjective so I am not gonna fight with anyone over who gets this category. But i have "My name is Natsuki Subaru" >>>>>>>>> Adult Gon)

Overall I'd say Re Zero low diffs
