Garry,
 
A Cockroft Walton multiplier always has the high voltage DC at it output
constantly available because it uses the positive and negatives swings of the
AC supply and diode switching to continuously charge all of its series storage
capacitance which is always hard-wired in series. 
 
In the Marx Generator the capacitors are wired in parallel through isolation
chokes or resistors and charged from a DC supply.  Once they are all charged,
in a rapid, simultaneous controlled breakdown of a bank of spark gaps the
entire array of capacitors momentarily finds series configuration and a single
HV output pulse is obtained.  Then a time factor must pass as the bank of
capacitors is recharged.  
 
Steady state relatively moderate current high DC voltage, or very high peak
current, single pulse DC high voltage.  Different generators for different
applications.
