Which is better?
One without the other.
Career and success in SFI, you can not do without PSA.
A CSA are you "like whipped cream on strawberries"
With PSA you personally are doing and are training them.
With CSA you personally do not have such a contact, because each of the CSA has its sponsors, but are always there - if you need anything.
Csa if it is active, it can bring you a lot of money.
