intuos pro M

When I'm trying to draw spontaneousely, it's like the pen is led by the top of the edges, my features aren't precises and deviates. Until now, I owned a Cintiq 26'' which was much better and I regret its precision. Before my Cintiq I had an Intuos 2, this one was also very good. Should I do some more accurate settings to draw like before or is it only a question of time and habit, maybe a better pen?

Thanks
