Which is better to pursue...CSAs or PSAs?

Like in most of the cases - BOTH! 

PSAs (Personal Referred Affiliates) are those who you personally introduced to SFI,and they registered using your getaway link.They are your PSA and you're their Sponsor.CSAs (Co-Sponsored Affiliates) are not the ones who you personally introduced to this company,but you're still connected with them and get a share of profit they make. 

From both of the groups (PSAs and CSAs) you'll have benefits.Little bit more from your PSAs,since their rank (EA2 or higher) can bring your certain amount of VP (from CSAs and their ranks you have nothing directly).Still,from both you will earn some money when they order something from Tripleclicks web store.If it's your PSA you will earn 45% of CV (Commission volume) and if it's your CSA then it will 15% of CV for you.Matching points can be earned from PSAs as well as CSAs (they all have to be EA2 rank or higher,and you have to be at least bronze team leader). 

All in all,you'll have benefit through: 

- direct commissions (45% for PSA and 15% for CSA) 

- matching points (if they're EA2 or higher) 

- versa points (only from the rank of your PSAs) 

Note that PSAs are yours FOR LIFE (for as long as you are and they are part of SFI) and CSAs are yours for as long as you keep achieving minimum EA status (1500 VP/month or more).In other words,you can be part of SFI and loose your CSAs,but you can't loose your PSAs (except if they opt-out on their own). 

Also,when it comes to sponsoring,to your PSAs you're at place number 1,and to your CSAs you're at place number 2.
