I'm not convinced of anyone making any sort of point by making a video first off regarding sound performance of a suppressed 556 (since they all suck and are loud), and second using a video at an indoor range to compare the two. There are about a million technical reasons that you can't compare level or tone from a youtube video.
Next, yes, one shot on the surefire does seem to have a large fireball on one of it's first shots, there are eight shots I saw flash from (in HD) with the AAC can. So.... I'm going to suggest that their claims of improved flash suppression are valid. I think this would require more testing to say anything about.
