Nope. Speculation is speculation. After Infinite Tsukuyomi, Koto is the next strongest Genjutsu, then goes Tsukuyomi. Sound Genjutsu just happens to work differently is all. Koto would catch anybody in it as a MS user like Itachi couldn't even get out of it if he wanted. Obito wanted it and he had access to the Rinnegan since he was going to take the Rinnegan from Nagato's corpse. Don't underestimate Koto.. though Shisui can only use it twice a day..
