Mine is actually a moving green squiggly arrow. Wait, no. I use mouse. It is easier in games, but I don't play that much anymore....
Mouse. It's a matter of precision. You can't have that much accuracy using fingers, unless they're pointed like needles. Also, you only use a small number of muscles to move a mouse(assuming you have one of these new ultra precise laser mouses or even a normal optical one) compared to what you have to do when using a touchpad. And It gets even worse with the new pads that support multiple fingers and gestures. You end up trading simple convenience for more tasks thinking that you're doing less. For example: -Scrolling a page with a mouse requires one finger. On a pad, if you're using a notebook, you have to move your hand away and down and finally scroll using the pad, requiring one finger and moving your whole arm.
For me it is the mouse because it is easily can be control and mouse is better to use when you are playing games
