What is the difference between IS and Taliban?

A lot of people fear ISIS and the Taliban, and these fears are not exactly unfounded. The Taliban and Isis are known to be terrorist groups, and they have a big chance of hurting different people from all over the world. They are also similar in the sense that they use the Sunni Muslim sects in order to create their own beliefs that are meant to hurt people in different ways. Obviously, they are two different groups.
They are both fighting to become the more dominant terrorist group. The Taliban is still considered to be one of the worst terrorist groups, but it is also obvious that ISIS has also made a lot of negative changes to the way that people live in the areas where they dominate.
