pen tool doesn't require you to have a steady hand though
it requires you to know how the tool works though, which i can't seem to get the hang of it yet. it is like making a shape, i remember there are other ways to use it, but the default way confuses the heck out of me. The other way I use it is to color in bigger shapes rather than lines. It makes life easy because you can easily change the color if you don't like how it looks into something else.
here is an image of me trying to end the pen tool but ending up making a big mess, notice how the pen tool works though, the overlapping parts turn the color into its counterpart. In this case it is turning white to black and black to white every time you overlap.

pencil and brush tool though requires you to have the steady hand since it is pretty much like using a pencil to draw something
