if you ask me i say recruiting affiliate to SFI is better that reffering TC members because when you reffer someone to SFI he/she automaticly is TC member too and if he/she wants to be successful in his/her business he/she must make a sale or purchase from TripleClicks...
but if you reffer someone to TC you can only benefit of for example his/her Tcredits order...but in SFI there many ways to get benefit from downlines...
