Key Board vs. Xbox/ PS controller

[yottabyte]

Personal preference is a thing. Keyboard and mouse is usually preferred for FPS' though, since you get faster response. I don't play a lot of console games but afaik it's usually easier to, for example, turn around quickly and then aim carefully with a mouse than a controller. If you're used to playing with a mouse, it gives you much better control of your sight overall. IMO.
