I am not familiar with the above mentioned products, the best I have found are my large wooden-pocks from Harmonix.
Keep in mind that while using green glue with dual layer of drywall helps with sound isolation, it will degrade your bass performance due to stiffer walls which do not absorb bass as well.
We use all dRC from ASC as well as 27 cases of Green Glue. The glue was not only applied between layers of drywall, but between all wooden joints and then screwed. No nails were used in all the engineered lumber. I also used 23 cases of acoustical caulking on all seams of floor/ceiling joists and wall studs. It was about a 2 1/2 yr. build.
As you can see, the ceiling is on Kinetics Noise Control spring hangers that were mounted according to the estimated weight in a predetermined location. What you're also looking at is a room within a room. There are about 3" between the inner and outer room. The 2 back walls are 3 layers.
We had a drummer hitting 130dB peaks in there one day and you couldn't hear it upstairs or outside. The stuff works!!
Thanks, Bruce. What is the black wrapping on the HVAC?
