Not Ranked

I can't speak to dyno numbers but I can say that on my flat-6 911 with Webers the MSD box made a substantial improvement in cold-start, idle, and low-mid range rpm manners. It also pulled more smoothly and harder to a 7300rpm redline.

My Cobra had one when I bought it so I can't compare before/after, but it also starts immediately on the first turn of key even after sitting and also pulls hard to 7K rpm.
