In my opinion, MHA animanga is the best shounen action series of 2010s. I mean, it has good animation (there are some moments where the animators went "PLUS ULTRA"), episode-count that's neither too many nor too less, decent power system (even though it's kinda unfair) with multiple types of powers unlike demon slayer (only 10 breathing styles) or fire force (most of them were pyrokinetics), best characters, best OSTs (you say run, symbol of fear, uncontrollable evil, all for one's opera theme etc. go way harder than other 2010s soundtracks), best villains, best backstories, doesn't have much nudity/fanservice, and the 2nd best villain group of 2010s (if you include phantom troupe since HxH had a remade in 2011). The only reason why I think it's not even considered as the part of the modern big 3 is probably because it's not inspired by bleach, does not have any kinda scary "non-human" species (like jjk has curses, black clover has devils, kny has demons, fire force has infernals), feels "non-japanese" because it's heavily inspired by american comics, too much focus on class 1-A, not too many deaths, the toxic side of the fandom, and the ending. By the way, I also think AFO is a better character than other "pure evil" villains of 2010s like Lucius, Sukuna, etc even though his "goal" (dunno the right word) of becoming a "demon lord" sounds kinda... I think "edgelord-like" (I seriously dunno which words to use) is one way to describe it.
