For the life of me, I can't comprehend why a PC gamer would go with a standard console-type controller. Won't you miss out on mapping the hotkeys? Having less than eight programmed hotkeys would drive me insane! To each his (or her) own, I guess.
I use a mouse + a Razer Nostromo N52 gaming device. I've been using the Nostromo series since 2004 and I've never looked back at console controllers nor keyboards since the switch.
Simple, controllers are simple to use, effective, and you don't need to remember where all the buttons are when switching game to game.
Also, if you set up the controller correctly, there is NO negatives to it. My controller is as accurate as I am with a mouse (more so even cos I'm just that used to xbox controller), I also have all 8 hotkeys, I have all the controls set up so everything is easy and nice to use.
That's why a PC gamer uses a "standard" controller. Although I'd rather use the term standard on mouse and keyboard.
Really, there is no better equipment, simply better set up vs left as default.
