There are different opinions on it, from what I have read.
For the type of insulation: some feel the Roxul type is better, some say the pink stuff is just as good. The pink stuff is quite a bit cheaper and from what I have seen/read, the differences dont justify the extra cost. However, the Roxul is SOOO much better to work with. So, it comes down to cost and convenience for me.
Actual difference in deadening is about the same.
