Personally, I do not think either is better than the other. It all depends on what you want to accomplish. In the end you will benefit from either. If you choose to sponsor SFI Affiliate you will build a network of Affiliates and earn commission from each sale they make. If you refer TripleClicks members you will benefit each time they make a purchase or if they join ECA ((E-Commerce Associates) So instead of preferring one over the other why not do both and your profit will be greater.
