Being from LA, I find the argument almost comical, the actual sound produced means nothing, no its all about the look! Like its a software fashion show. But anyways terminatorX has a cool looking GUI and runs even under my crummy system. Hydrogen looks great, but terminatorX will run on systems too slow for hydrogen. You can use jack, or not and go right to alsa if you're having performance issues with jack. http://terminatorx.org/
