As a lifelong member of the glorious PC Gaming Master Race AND an owner of both major consoles I will say this:
The PC will ALWAYS be the better platform for the FPS because, yes, the mouse'n'keyboard give you a much, much more rapid and accurate response than a controller ever will.
THAT SAID.
In the context of the consoles (and there is nothing wrong with playing a shooter on a console, guys) I think that the Xbox controller is almost invariably the better one unless you have abnormally large hands. It's more ergonomic and the placement of the left thumbstick above the D-Pad makes it much easier to hold in a neutral position without any tension on the thumb. The triggers are also better, but the new position of that thumbstick (and the shortness of those thumb sticks in general) make the Xbox controller much more suited to the FPS than the PS3.
...which is a shame, because the PS3 is a better console in every other way. If Xbox kept the same basic design (I believe they did) then they have a leg up on the Dualshock 4 in the FPS market just by virtue of it being easier on the thumbs. In every other respect, though, I like the new Dualshock controller better, and the addition of shorter, concave thumbstick and a more curved grip is going to be a huge boon; I just modded Xboc thumbsticks onto my PS3 controller and let me tell you, it's a aorkd of difference. If the triggers aren't spongy it's going to be golden.
As far as the touchpad is concerned, I actually think Sony has an advantage over the Xbone for other genres. One of the things I had the most trouble with going from PC to Console with the Mass Effect games was the lack of power availability. The whole power wheel was sort of a joke in the PC version because you had 8 open slots on the number keys you can hit with finger 2, 3 or 4; you didn't need it for anything except giving commands (and if I recall you can hotline those too). In the console version I was using that wheel like mad, because you only get two buttons. For Soldiers and Infiltrators that's okay, but Adepts and Vanguards are sore out of luck. If that touchpad can be used as a sort of virtual button array or as a sort of quick-access inventory screen it's already solved a lot of problems with the console interface - you now have a significant number of new virtual controls that can be reconfigured at the developer's whim. THAT makes me excited; the possibilities for RPGs are very diverse.
