Clearly, mouse and keyboard is the best aiming method. But, it requires one to be seated in a somewhat specific manner. Dual analogs are the only good way to aim while laying back on the couch, or in bed. This is basically the same thing that separates PC from console gamers. PCs are clearly technically superior. But, if you're going to hang out on your couch and game, consoles do that job better.
(yes, I know that you can hook your gaming rig up to your TV and use a DS4 or XB1 remote. But, at that point you've killed a good chunk of the PCs advantage, and paid a lot more for the experience)
