The ease of use, especially when using multiple referrals at once! I like that there are so many options to customize your dashboard as well - it's easy enough if you know how but even those who don't have an idea where they might want or need help can figure out what works best with their needs/situation very easily by just looking around in different areas (I'm not sure about other programs).
It takes some time getting used to all features; however after spending several hours customizing my dashboards everything started working smoothly afterwards.- Multiple referrers per account & accounts themselves.- Easy integration into email campaigns such as AWeber which makes reporting much easier than having separate tools set up specifically for each client / network member etc. This also helps me keep track better because now every new user has its own unique ID number instead of being assigned one from another.
