^ Exactly, it is improbable that Sasuke has tailed beast level of chakra. Both of Sasuke's rinnegan and mangekyo abilities require a decent amount of chakra. It's more about how well you can control your eyes. Look at Itachi. He was know for having weak stamina, yet he could still pull a Susanoo at the end of his fight with Sasuke. The same with Sasuke during his fight with Danzo. Also, Naruto doesn't have either tailed beast level of chakra on his base level. He most likely has more chakra than Sasuke, but certainly not at tailed beast level.
