His wife,His Teacher and His so called best friend knows all about Six Path powers so knowledge point is moot
About skill part Sasuke used the strongest Rinnegan jutsu CT just few hours after awakening Rinnegan :lol
that is because he witnessed Madara before :lol
he used his body to shield the blades :lol
he only has 1 rinnegan so far, so my logic stil stand cause he has not used all to this 6/7 paths:
Half The Deva Path (天道, Tendō), which allows one to manipulate both attractive and repulsive forces.
The Asura Path (修羅道, Shuradō), which grants the user mechanised limbs, weaponry and armour.
The Human Path (人間道, Ningendō), which gives the ability to remove a soul and so, read a person's mind.

The Animal Path (畜生道, Chikushōdō), which lets the user summon a wide variety of creatures.

The Preta Path (餓鬼道, Gakidō), which can absorb all forms of chakra, including most ninjutsu.
The Naraka Path (地獄道, Jigokudō), through which one can summon and control the King of Hell.
The Outer Path (外道, Gedō), which rules over both life and death.
