From my perspective on gaming, this question or inquiry is fixated on PC gamers mostly because they are the ones that makes use of mouse to play with their PC games. There was an argument I saw online long time ago on which gaming control tool is more accurate in targeting between mouse pointer and console pad controller, and from gamers views, it was deduced that mouse was the best.
So, as a PC gamer like myself, I prefer using mouse to play then using touch screen. I can't imagine it being possible to have gaming satisfaction with using touch screen to play.
