Some factors matter more than others. TTK is pretty much the major factor determining what gun people use. Recoil doesn't matter on a gun whose TTK is extremely small, as chances are you've killed your target before the recoil gets the better of your aim. You can't use pure mathematics to prove anything, especially in a game where lag, which can't be factored into any mathematical proof, plays a major role into who comes out on top.
