Keyboards and joysticks separate the boys from the men.........boys mash colorful buttons and twirl sticks while men use a wireless mouse, high sensitivity, and a erganomical key layout. Mouse is more accurate and is more percise. Keyboard has more hand combos for more kinds of people. You can move and reload and use at the same time without slowing down. Joystick is less accurate and percise, so there is some autoaim involved. The buttons will separate your thumbs from the important joy stick. Although there are triggers, the mouse has everything connected to the shoot button, making firing upon an enemy a little easier.
