DUI + optimized ignition curve, integrated assembly, simplified wiring, performance electronics, consistent hot sparks throughout the rev range.
Keep in mind that the DSII is an "emissions control device" designed to provide a consistent spark for 50,000 miles, not a performance distributor. To optimize it for higher performance you need to do more than just take it out of the box. It is far better than points, however.
Can you make a DSII work as well? Sure, but you need to spend a good bit of time figuring out how to recurve the thing properly, add a decent ignition box, find a good coil....
