I agree CC that you should just watch either anime, but I would contest that there is no value to the manga. CA arc's narration is objectively definitively-in-my-humble-opinion better in the manga and it is impossible to replicate it or improve it in anime. This goes for most narration-heavy manga. It will never, ever happen. That being said, 2011 didn't even do the best that it could've done in that regard.
I could also point to lots of significant scenes in which the 2011 anime's hokey mood often fails to capture the tense/visceral atmosphere of the manga or just falls a little short (mostly in YN and CA). 1999 anime is usually a little better in that regard but it has its own failings from what I remember. Certainly both anime adaptations are superior overall and for a one-and-done experience, watching 2011 alone suffices to definitively experience HxH, but there is value in examining the source and in this case it is, imo, disingenuous to suggest that the source has no merit in its own right, chicken scratch notwithstanding.
And yeah, reading is faster too I guess. That being said, I don't have the time or desire to read this shit either so I'll pass. I'd also rather just watch the anime again.
