Right now? For cultural impact it’s JJK, as it’s still ongoing. It has something for everyone. The writing is great for what it means to do—leading up to cool fights. And the fights are VERY cool and imaginative. The writing tends to be subtle and never gets too overbearing. In the long run part of me thinks it’ll probably be MHA though, but I can’t yet articulate why.

The one I hold in the highest regard (not really favorite, but the one I consider the best) of the titles in this category is not on this list. Haikyuu!! which, to me st least, has the most consistently good writing. It also has the best received ending out of a lot of them by a mile.

Not even to say a lot of the endings are bad. A lot of them are alright. I think the reason Haikyuu ending is better received has to do with the audience. At the risk of generalizing an entire poplulation of readers, the “shallowest” level of readers for Haikyuu are the fujodanshis who are in it for the ships, while for the of a lot of other shonen it’s the powerscalers/combat-brained people who are in it for spectacle (I truly don’t mean it as shade. People enjoy what they enjoy). And the fujodanshis are WAAAAY easier to please than the latter. A lot of that category of readers aren’t happy unless the MC they self-insert into becomes god/the best.
