which justu is the most versitile?

[Juto4432]

Hiraishin no Jutsu (flying thunder god). I don’t know I just like teleporting. Leave a seal at home so I can immediately get in to bed after school. And it seems to work great in fights.

Creation of All Things, like some have mentioned...
Other than that Gaara's jutsu that allows him to use sand is a very versatile jutsu.
