See, I said nothing of speed, but intuition. For me the pressing keys to move is just...off. It feels weird to me. Now, pushing, that feels better. The one thing I will give PC set-ups is the special functions: you can have faster, better access to more of them. Things like switching between 10 (or more, you can set it up so that you use a scroll wheel to switch what the numbers do) guns/ammo types/etc. just using the num pad, rather than pressing side on the d-pad multiple times. But this problem goes away in games without many special functions (ignoring the possibility of added functions because of this lack of ability). On twitch kills: not my cup of tea. I prefer a smooth turn rather than the jerky ones. That's one of the main reasons I don't like FPS on PC actually.
