I'm going to make this as brief as possible. Sound Genjutsu does nothing to your senses, but "mediocre" paralysis. Basically, it prevents you from breaking the Jutsu. That's only a hypothesis. Being inside of a Sound Genjutsu still allows you to use your moves. It's like they're still in reality, but outside of it. Sharingan Genjutsu can make reality. Often times, they were completely aware of their surroundings. I'm too lazy to look for scans, but I'll tell you the scans to look for.
Example:
- Itachi and Sasuke was able to perform their Genjutsu.
- Shikamaru was able to perform his Shadow Jutsu to break his finger.
- Pain still had control of his other bodies.
Temari was able to blow the Sound Genjutsu away. If you had a move that could disrupt your chakra such Shikamaru's Shadow Jutsu, then you're still able break the jutsu.
Sharingan: Genjutsu is a bit different. Often times you won't even realize you're in a Genjutsu. Inside a Sharingan Genjutsu you don't have access to your moves, and allows you to control your opponent, your opponent senses, paralyze, or put to sleep. Downside it, breaking it is not impossible.
Overall, it all depends on the situation in which the jutsu is being used. Saying it's greater than Sharingan Genjutsu is stretching it.
