HERE is the data sheet on those, they are Nichicon PM series caps. They are the best series that have 35v rated.
The 330uF has 0.06ohm (100khz), and the 1500uF has 0.024ohm (100khz). So five of the 330uF to get roughly the same capacity as the 1500uF will get you 0.012ohm, pretty good.
I am trying to decide between these. :024:
