They have the same aim assist. Same aim assist. Same recoil reduction.
What is the point you are trying to make? You claimed that consoles gave quick kills. That is net code, not aim assist.
As a keyboard and mouse xbox player, I disagree that the TTK is better. Are you implying that the netcode has some hidden function that if it is a console and is using a controller, the damage is increased or netcode favors the controller-using console player instead of the controller-using PC player or keyboard-and-mouse-using console player?
I am having a hard time userstanding what the claim is. Your claim seems obviously to be a claim about netcode or a damage boost favoring console. But you keep saying aim assist. I'm baffled.
