Obito and NAgato both had Sharingan or Rinnegan so it is logical that they can scan you with it

it wasn'T shown how detailed Naruto's chakra senses are (if he can only sense the whole body chakra or chakra which is gathering arount somenes eyes)

Sasukes arrows are quite faster than Naruto could ever move in Sage Mode even if he could predict that Sasuke is up to an attack Sasuke arrow would be much faster than naruto (when he reacts at the same time the arrow is released) (and when he reacts before Sasuke releases the arrow, Sasuke could see Naruto's movements and shoot at the predicted area)

yes the usage of senjutsu is different but i gave 2 possible power ups to Sasuke with which he would be equal to Naruto in his Sage Bijuu Mode (Susanoo with Juugo and Armored Susanoo)
