which of the mainstream action mangas has the best art? whatever I say is correct, so all of you have to listen to me here.

Hard disagree, Berserk isn't even debatable.

Bleach's art wins, hands down.

Your subjective preference is statistically irrelevant to objective visual analysis.

Jujutsu Kaisen. Gege's paneling and fights hit different.

Dorohedoro isn't mainstream enough for you plebs to handle yet.

Claiming you are automatically correct is an objective falsehood when Yusuke Murata's work on One Punch Man exists. The perspective and literal flipbook paneling in his action scenes are a proven technical masterpiece, so your opinion is officially overruled.

Berserk. Everyone else can keep polishing speed lines while Miura casually carved a cathedral onto every page and made ink look expensive.

Cleus, Gege literally published unfinished storyboards, your take is objectively delusional.

Vagabond is what happens when ink gets tenure.
