Personally, I think that using SFI is better especially if you are contacting a group of PSAs and/or CSAs. I say this because you know the list accurate. It contains all of your downline and gives you a great way to filter them. If you have a large downline and are maintaining you own mail list, it is very easy for your list to be inaccurate. People are deleted because of inactivity, people are added below your first level which you may miss adding to your list. Plus you do not have all the information to filter your mailing as well as you can with SfI mailer.
If you have a small number of affiliates, your top performers for example, that you contact often, I would maintain your own list.
