4 Wall designs… Which is more effective?

I am trying to decide which wall construction would have better isolation performance for the interior wall of my studio. This second wall is on a floating slab. My exterior wall is already finished.



This is what I am deciding between.



1. 1 layer of 3/4 inch OSB (recommended by builder for sheer strength), Green Glue, 1 Layer of 5/8th Sheetrock.



Or



2. 2 Layers of 5/8th sheetrock with Green Glue.



Or



3. 3 Layers of 5/8th sheetrock.



Or



4. 1 Layer of OSB and 2 layers of 5/8th sheetrock.



According to this PDF on Green Glue, it appears that either #1 or #2 would be most effective. But of course, this is coming from them.



Any suggestions?
