Well, it's really hard to call anything better...that's all a matter of opinion/personal taste. The weight difference, I believe, is due to the weight of the driver in the SVS, as well as the cabinet being slightly bigger. And yes, the continuous wattage listed is more for the SVS. But again, all of these things don't necessarily make one better or worse. I researched for about a month before buying mine, not only looking at hsu and svs, but at a rocket ulw10, an adire rava among others. For me, it just seemed like I was getting the most for my money from the SVS.
