In the examples shown by the table inserts I would say there are better ways to get where you need to be then draw. One advantage to using draw is that it is easy to control the path of the cue ball and opens up a wide variety of throw options on the object ball however controlling distance traveled ofter contact takes some practice. In my opinion drawing the ball the length of the table (or equivalent) has more advantages if you are breaking up clusters or are in a situation where balls block the path of the cue ball otherwise. Being able to use draw at all levels including extreme helps to move the cue ball at a 90 to 140 degree angle after contact. So in my opinion the control of draw is the most important but it is an asset to be able draw the sh%t out of the ball if the need arises.
