You can pick a controller layout like that but im still gonna go with the CoD layout that has smart as sprint on the left stick. And most fps games do not use the d-pad to switch weapons, most fps games use triangle or Y like CoD.(CoD, some Battlefields, Section 8, blacklight, MoH, ect.) Also i find PC fps gaming way more difficult then 360 or PS3, the main genre i see PC being better at are rpgs and mmos(though those are still fun on console)
LoL You realize that a mouse and keyboard has much more precision and control than a gamepad and that consoles have autoaim? Also that consoles have about 50% if that of the graphic capability of a high end PC.
Its all about what you are used to. Consoles are just for gaming so its easy to jump right into. Pc Games is general have more depth and control. A high end PC gaming PC is also much more expensive.
All new FPS features almost always come to PC first and with PC you typically have more features and customization.. Like I said its personal preference but a keyboard will always have more buttons than a gamepad.
Its really nice in brink that you can customize your layout and button configs.
