Bull, I had the same experience as you when it comes to the Superkick. It was quieter, and I found it very generic and one-dimensional sounding. I couldn't tolerate it, lol.
I understand why people do like them - they produce a usable sound very easily, a sound that is very easy to mic up. It just sounds too bland and boxy to me, though.
The Force 1 heads sound good if you want to stick with Aquarian. Much like a PS3, perhaps a little livelier.
