I cant say I compared the two of them directly, but I did compare it against other budget subs at Best Buy. IMO it provided the smoothest cleanest bass of all the subs they had. I compared it against the Kilpsch 450 350, polk psw110, psw111, psw10. It didnt hit as hard as the 450, but it was much cleaner sounding. No where near as boomy. I had BB price match Newegg and got two of them for $79. Granted they are no pro subwoofer but they are a hell of a deal for a budget musical sub.
I run them off of my preamps main 2 outputs to help improve my mains low freq in 2 channel. Its a hybrid system so they are also part of my HT setup. They blend well with my dsw600. It was a very impressive experience with Dark Knight Rises.
