I don't know.. A gun would be quicker depending where you get shot but a knife suffer more because that person could keep stabbing you so i would rather get killed by a gun but what place would you like to get shot in order to die... What would hurt worse or hurt less??

I'd go for a knife. Think about it, no matter what, you're going to see who stabbed you. If they stab you from behind, you've still got plenty of time to twist around and see who had so much hatred for you, that snuffing your life out was the only option that could possibly do justice to whatever you've done to upset them. You also won't have to ask the question of "who" once you reach whatever afterlife you hold to be true. ; )
With a gun, the person would be halfway up the street and you'd catch a nice view of their backside, if that, before you hit the ground.
A knife..
At least I would be maybe in come kind of position to get the bastard who stabbed me in the first place.
Getting shot just finishes u off with all the shock but with a knife wound one still has fight left in em
