Don't let Micah's bluster fool you, Micah is an incredible gunslinger, just look at how he handeled himself while shooting up Rhodes, but Arthur would still win
John’s drawing speed in RDR1 is unmatched. RDR1 John would kill both before they even started the draw. If we’re talking only RDR2 then I’d say Arthur. No reason. I just really like Arthur lol.
Considering the sheer speed of Micah in American Venom, realistically I'd say him. John was only able to kill him because Dutch shot him off guard. Even in a two on one duel, I'd likely say Micah
