Fatmat and RAAmat are comparable products I believe.

Once you have your brands narrowed down.

What to pay attention for when buying deadener...

What base? (Butyl or Asphalt?)
Thickness? (mm)
Material? (Sq Ft)
How much? ($/Sq Ft)

That's how you will get the most for your money is by comparing the thickness of the sheet along with square feet you are getting for how much you'll be spending.
