Randy, the clips would do a much much better job than two layers of GWB with green glue in between. I would not expect any appreciable difference from two layers of GWB, compared to two layers of GWB with any type of resilient glue in between. I have seen test data, and installations, where the contractor has mistakenly put the RC in between the two layers of gyp instead of in between the joists and the 2 layers of gyp. The results are as if the RC is not there, because the cavity isn't large enough for the resilience of the assembly to have an effect (or affect)
Quietrock, while it is a worthwhile product that has its place, it is very expensive for what it does...on the order of 8-10x what a normal sheet of GWB is, like the other Matt said. IMO, in most cases you are better off slapping on additional layers of GWB instead of paying the premium for quietrock.
FYI (and IMO) Their marketing and test data, albeit accurate, doesn't exactly present an apples to apples comparison...
