Uhh, what about the most important test. What does is do for sound? I've used one of the other kind of sound deadeners and it was butyl based. In the cold it turned hard like plastic, hence no worky. My dynamat extreme didn't do that. I don't know. Dynamat has worked for me in the past. Even if it's the most expensive, so what? At most it's 500 bucks to do your entire car, forever. It's not like going with a subframe that winds up not performing like you wanted. Just a few buck compared to all the other equipment we have in our cars.
