Inductive vs Capacitive Discharge

I am a little lost as to what the difference is. The MSD 6A and i believe all MSD are capacitive discharge, while most of the Crane Cams are Capacitive Discharge as well. However, Crane Cams offers an Hi-6S igntion box that is Inductive Discharge. I seems like it claims to do many similar things (20 degrees crankshaft rotation up till 2,000rpm) and mutiple spark.
The Crane Cams HI-6S and the MSD 6A are priced almost exactly the same. With the exception of the Crane Cams being fully digital vs the analogue MSD, and the Crane Cams being inductive discharge vs the capacitive discharge like the MSD.
Basically my questiosn is what is the difference betwee inductive and capacitive discharge and which one is better?
From what I can understand, inductive just uses a really big spark, while the capcitive discharge has a weaker spark, but at low rpms can generate them a lot faster.
What confuses me then is that the inductive HI-6S claims to be multispark as well. Here are its specs:

I am really stumped.
