Both are good. CSAs a given to you for achieving EA status or can be won at auctions. PSAs can also be won at auctions but you can also recruit PSAs on your own (friends, family, posting ads etc) The both have the same disadvantage of inactivity but when you are fortunate to get active people in your down line, with CSAs earn a 15% commission and PSAs a 45% commission. With PSAs earn matching vp to 12 generations. So the both have their benefits. I recommend both!
