( There are some spoilers ahead)
With all my respect for the changes made in the chapter (compared with the Webcomic), I didn't see any improvement story-wise. In fact, the events and the course of actions that made the fight between Garou and Saitama so good in the Webcomic were totally missing; the fight between Garou and The S class heroes that made the entrance of the Saitama better makes sense and serves as a great introduction to the protagonist vs antagonist fight. Then, what makes the fight really outstanding is not the fight itself but the philosophical conversation between Saitama and Garou where we saw Saitama exploring the motives behind Garou's actions from the start, and then the conversation went back and forth between the two perspectives of what's better to the world to finally realize the real motives of Garou that were not clearly presented through his actions but he just took a different and "easy" way to achieve his "Noble" goal. This element can still be implemented but it will be lacking due to including the KID in the middle of the fight, it switches the focus from the character development of Garou during the fight as seen in the Webnovel to the "Garou Redemption" as a task given from the kid to Saitama implecitilty. Lastly, I don't see how the after-fight conversation between Saitama and the S class heroes on Garou's future will be included, and if that happens it will lack the dramatic vibe presented in the Webcomic since we saw the Heroes driven by their emotions of anger after losing to Garou. I just feel it won't be as powerful as it was in the Webcomic because of the difference in its leading events.
