John Marston vs Jack Marston

5 days prep. Full ammunition. Every weapon except Explosive rifle,dynamite,and fire bottles. Bloodlusted. In Armadillo.

Stalemate

I'm thinking Jack takes this. It's a hard fought battle but in the end John is currently dead so that takes it out of his favor.

I'd go with John. The game was about him anyway and he's the more detailed and harsh character. Jack had a hard life since his dad was killed but John had the outlaw/gunfighter life that was defined through thw real old west, which was extinct by the time Jack grew up. That poise and prowess in gunfights is why I believe he takes the cake
