I like that it will send out emails with multiple recipients in one go which saves time sending them individually (rather than having to wait until each individual email has been sent).
It can sometimes get confused when trying to do different things at once but this isn't too much of an issue since you have options available if something doesn't work properly or goes wrong. We use linked prospect mainly because we wanted to automate our invite process so they were able to set up all of those automatically without us needing to spend hours doing it manually!
