that's very difficult to answer in the right now the manga follows one story after many redraws (almost 1 to 1) but at the same time the manga gives a bit more interest to certain fights and stories for examples a bit of Saitama's past that isn't in ONE story, Boros's fight that wasn't as epic in ONEs story due to lack of drawing skills and building it as ahh i killed him what is next, all of Garue's arc being different in ONE story which led to an awesome fight against Garou while in one it was about Saitama belief in heroism (or the lack of it xd) after that it looks like the manga tried to continue independent without ONE story but didn't succeed and gone back to ONE storyline if the manga story was 1 to 1 ONE story i would say that the manga is better due to better drawing, but cus some stories in the manga doesn't follow ONE story i think that overall it's better to read both while ONE story is superior cus in the manga then cant follow ONE story to perfection cus of god, Boros significance (comrade to blast) and Garou fight. i have no idea how will the manga address this while following ONE story
hope this helped you
omg thanks for the explanation
i was pretty confused while read the repeated redraws n lost trach of where the story was going, thats why i thought maybe sticking to just 1 version would be easier, but as u said, whether its ONE or the manga, it really feels like i have to read both since they complement each other

Which one better?
One version or murata version?
