Roxul Rockwool or Owens Corning Thermafiber

I have dived into the world of room treatments again and going to build my own. Starting with some high-freq panels. In the past, I used Rockwool for bass traps but I'm having a really hard time finding it now.

I see that Owens Corning came out with a new product called Thermafiber and it sure looks like it has many of the same sound absorbing properties as the Rockwool.

I cannot find a direct comparison. Does anyone have any experience or knowledge about this stuff?
