Chimera lacked fun of any kind. It was dark, brooding and mostly depressing. Felt like a standalone that was completely cut off from what made the previous arcs so loveable. I was feeling more relieved that the arc ended than satisfaction of having watched it. I've went back and repeat watched most episodes in other arcs again one time or other, but never Chimera.Yorknew and Chimera arcs were pretty dark imo. Deaths in this anime are very painful and leave a real sour taste in your mouth.
Surprised you think Chimera arc was boring though, but opinions. All HxH fans, including me, consider it the pinnacle of the series and it's definitely the most arc that fits the "Hunters" theme of the anime. At the end of the day the Hunters organization was founded to search and find this kind of mysterious creatures and places.
Green island was the most boring arc for me tbh, because it was all talk, though the fights by its end was great and redeemed it a little bit.
Yorknew and Phantom Troupe are the same, right? Heaven Arena would have been my choice of best Arc.
