If done right actually, hanging can be the best way to killl someone. When the rope jerks and breaks the person's neck, they die almost instantly suffering a second of pain. In injection it takes 2-3 minutes to kill them, but the calculations are more accurate most of the time.

So really it is just a matter if the person killing you is an idiot and doesn't know what he is doing. There is a lot of thought that goes into a hanging now.
