The difference between having a power and not having a power, is much much greater than having either power or slightly more. IE, having one sharingan is a great leap of power from having none. Having a second Sharingan adds more power, but not nearly as much. Kurama already gives a bunch of power, adding some more from Ashura or Kushina does not nearly add as much power to Naruto. It would've been far more shocking if Sasuke were a jinchuriki or of Naruto had a Sharingan.
