What is the best way to make Paper Mache Paste?

Because I have been searching on the internet to make it, and there is 3 different ways I've seen the most. One way is with Flour and Water no-cook. Another way was Flour and water and boil it or something, and the other way was Glue and water. Which would be the best way to make something that's not easy to break if u bang it against the wall and run into people with? The most sturdy & unbreakable. And if so, could you also tell me if it is the flower, how much flower to add & how much water (the proportions).
