I like that it is very easy to use, you can create different types of stories in minutes! It's also really good for creating content ideas or inspiration boards so we have something tangible from which our team will be able build out their own creative briefs/ideas etc - this way there isn't any confusion about what they are trying achieve as well as having some kind of visual representation helps us communicate more effectively with clients too.
The only thing i dislike at present would probably just come down to my personal preference but if anyone has suggestions then please let me know (I am sure others may find them useful!). We used bda before starting work together now its one tool where everything comes back into contact because all parties involved always seem happy when using it again after working remotely.
