He has EMS because of Itachi's eyes which are not his own. And how are EMS and SM similar when Sasuke gained the EMS for free using Itachi's eyes while Naruto had to work his ass to get SM. Now I can give a lot of scenarios where Sasuke has relied on external powers and none of them were genetic abilities. Then we can compare who relied on external powers more.I don't see how it matters that he has the EMS, it's like getting on Naruto for having Sage Mode to avoid losing his right arm from using the Rasen-Shuriken.
