I'm afraid I can't compare it to other bikes with different systems, but it performs the same as the original system with points, without the hassle of points.
The bike starts very easy and runs very well, it probably has a stronger spark.
As far as I can tell with my strobe light, my system doesn't have an advance curve built in.
(The German site also doesn't seem to mention that their system has an advance curve)
When you're in the the neighborhood, you're always welcome for a test ride.
