I must say... The Ten Tails Biju, as we all know is the most strongest out of all the Bijus. This is well to be expected though as the others were brought from it. If the beast is powerful, we can't expect the host to be weak. As the very embodiment of Nature and Senjutsu Chakra, Ten Tails has given an outstanding Upboost to every Ninja that hosted it. First with Kaguya, then with Hagoromo, moving to Obito and lastly Madara. Even though the war is over, this ninjas has left a reputation, either good to bad or bad to good, which clearly shows their power level difference to the likes of those who hold the 1-9 beast, including Naruto {of course this was before he acquired an Upboost from Hagoromo}
