Hope this chart is helpful to someone. 2-inch is what I chose to go with in my tiny studio. The prices are in Nashville, TN

If specs are all you're looking at, go with John Manville for 3.0 PCF high-freq. absorber and Knauf for 6.0 PCF low-freq. absorber.

Glad to see others checking out the JM products. I've talked about it several times but no one seemed interested.

FYI, I'm paying 75¢ a sq. ft. for the 2" JM here in Fort Worth.
