As stated above, they are both the same techs. Sasuke has learned to use his to help him fight in plenty of combat situations, ranging from long range sword to thrown projectiles and to emiting it out of his body sort of like nejis palm rotation. That shows that while they are both the same techs, sasuke has greatly improved on it. Also, i dont recall kakashi ever using a black raikiri.
