I would say that there is schranz and then there is also hard techno personally. I think that generall Schranz is a bit more monotone, and generally a lot faster than hard techno. Sometimes the tracks can reach into the 160BPM range. Which is quite fast for if it was a hard techno track. Then there is the obvious over use of distortion...because I have said it once before...Distortion does not equal hard, but only the mood created by the tune itself. Don't get me wrong in that respect either...Distortion is a very good weapon if used properly and not overused. But if it's too heavy just makes things hard to listen to.

So to put an end to my rambling, yes there is a differane. Atleast in my humble opinion.
