It's my first time reading the series. I heard a lot of great feedback about it, but wasn't ready to start an ongoing series with way too many hiatuses after D.Gray-Man fiasco (by now I dropped the series since I forgot what was happening there) and Nana (on hiatus since 2009... Eh). Also, not sure where we are with Black Lagoon, it also seems to have an irregular schedule, and I've stopped reading it by now after finishing one of the arcs there.
But everyone here encouraged me to try HxH, and I'm glad I did. It is really interesting, the characters have great development and I like that we have a lot of focus on several of them, and it's not like OP or Black Clover, or Bleach, where you always need MC to hit the BBEG.
