Naruto jutsu, since so many other combinations and additional effects come with it.
On the other hand, Kisame with his water world ball could top this, yet again Hashirama being able to use Mokuton, can also use earth and water jutsu, hmmmm, oh and supposedly the 1st liked to use swords, now that would be a fun fight ;D.
Hmmmm, perhaps Naurto will once have a similar territory jutsu, for example producing a gigantic ball of wind spinning around him and his enemy and then utilizing it to strengthen his jutsu and allowing him to attack from every direction he likes ?
Konan's origami ocean could fit this category as well.
BTW. Don't you find this funny that Senju were seemingly the only ones that were using armors before the creation of ninja villages ?
