The only reason I've put Ne Zha & Daji for assassin counters is because of their ability to cancel his combo. Ne Zha counter with his ult if you pull him in plus the double sash combo. Daji's 2 can cancel his ult knockup. Take this with a grain of salt bc it always comes down to the player. Regardless, other than the gods mentioned above Susano is practically good against any other god in the game.
