Ok so for bows, I’d like to Nominate
Sagittarius Aiolos. The reasoning is as follows - For one, all of his attacks are precise enough to target matter on a level below quarks.
He is vastly more skilled at marksmanship then Aquarius Camus, who casually pingponged a projectile from Greece, to a star around 540 light years away, back to Siberia, without looking at it. This is more impressive when we consider that the star, and earth are both moving.
In addition, Aiolos’ previous reincarnation, shot an arrow from Greece, to Germany In a way that if it was spilt into 4 pieces, they would exactly hit 4 separate floating targets, while the bow string was also being pulled back by a person who has never shot an arrow in her life.
Sagittarius Seiya, who has pretty much the exact same skill set as Aiolos, shot an opponent though the chest with an arrow, all while compensating for the fact the target was standing under a mass with a gravitational field comparable to a planet.
Finally, Aiolos also sniped his brother who was on earth, from space. While this wasn’t with a bow, it’s a general marksmanship feat.
For placement, there’s no one on bows category rn, so first place.
