I use a controller. I know people will say KB&M is superior, and it very well may be, but I'm a controller guy through and through. Some annoyances. Aim resetting to 0 degrees after moving, fine aim (especially when scoped) not being separate, but all in all it's more than playable. I'd suggest anybody that has doubts try out either for a month. Get comfortable, learn the ins and outs. It depends on the player to find out witch they thrive with.
