This is a good point, but narrative-wise, for every little nice thing the manga brings to the table, it endlessly dilutes the storytelling with tiring, redundant, largely inconsequential battles and encounters so much more. For example, do you remember how many times the monster cells in the manga?
Four times: at the martial arts tournament, in the Hero Association HQ, at Atomic Samurai's meeting with his acquaintances, and once more with Sonic and the Ninja Village alumni. Why couldn't it have been cut to at most two instances, considering only
one of them actually mattered long-term? The entire martial arts tournament is just a waste of time for everyone; the jokes aren't even good, the twists are cliche as fuck, and none of the new characters matter (we will most likely never see them again). Most of Garou's hero hunting is also glorified filler. The only entirely new fight that had narrative consequences for his character is the bout with Watchdog Man (which, ironically, happened offscreen—while less important fights were drawn in full).
So it's not so much "more character-interaction-driven" as it is just
having more of everything—but not equally so; most of the new content doesn't actually flesh out any prominent characters. I mean it's just my opinion, but I would've sacrificed most of it readily for tighter, more dynamic, less shounen-y storytelling and I can argue at length—and have done so elsewhere—as to why it would've resulted in a superior reading experience. I love OPM and I consider the webcomic one of the sharpest and most interesting character studies ever written in the superhero fiction genre; the manga mainly works to turn it into just another good shounen action series (and don't get me started on the anime).
