itachi killed shisui therefore gaining what we see right now.
Sasuke was about to kill naruto to gain MS but decided to go a different route.
Kakashi is Good. there through Hard work he gained a good version of MS.
Think of the force in star wars. Jedi uses the light side of force, sith uses dark side of force.
ALSO. Kakashi's version MAY beable to beat itachi's version.
Orochimaru said in the forest of death that sasuke's eyes is deeper than itachi. Through that we can ASSUME orochimaru see's sasuke gaining the Good MS and not itachi's version.
In terms of numer lets look at it like this.
Itachi's version = 10 and will stay 10 forever along with bad eyesight
kakashi's version = 8 But has POTENTIAL for being 11+
