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

I would pursue both Personally Sponsored Affiliates and Co-sponsored Affiliates

You will receive more from direct commissions of orders placed by PSAs and new cool badges to your SFI affiliate center. However you will also receive commissions from orders from any of your CSA at about 1/2 of the dc rate
