When you have an issue, there is someone to help with that problem immediately! Very fast response time for all of our needs - from scheduling meetings or just helping out when we need them most (like now!).
I think my favorite feature so far has been how simple they can make managing your budgeting/accounts easy too!! Nothing as much yet though but if something does come up then i'm sure their team will get back right away :) My main concern at this point would be getting more clients onboard
