Sorry, but I just had to correct this. The Susano'O that Sasuke used against danzo was his Incomplete Susano'O.
Susano'O levels seems to go by this pattern
1. Ribcage Level (although their are small levels of deviation)
2. Skeleton (What Sasuke used against to destroy the pillars and what he used initially against danzo)
3. Incomplete (What Itachi used against Chibaku Tensei, What Sasuke used after he broke Danzo's JuinJutsu, and What Madara used when he made the Mokubunshin.
4. Complete (What Itachi used in his ecounter against Sasuke, and what Sasuke use's in the Scan im about to provide as well as what EMS Sasuke has)
5. Perfect Susano'O (Obvious)
We can see here that Sasuke leveled his Susano'O to its complete form. What Sasuke had been previously using was an incomplete Susano'O
