Jinbei is known as one of the strongest water users in all of One Piece, but despite that he does end up taking a lot of Ls. His judgment is usually what holds him back and that’s a dangerous down-side when going up against someone like Garou. You need split second reaction times to take him on and I’m afraid that Jinbei is simply out of luck with that this time. Garou beats him in all stats so Jinbei will ultimately not last too long against such a fierce foe. Garou wins.
