I have been using their service since 2015 when my boss was looking into what are best services regarding online video marketing (specifically Youtube).
The interface looks very clean as you see nothing but green boxes or videos which makes your work easier especially if there's so much content out here! Not sure about others features like API integration etc.,but i really love how easy-to use its UI compared other competitors offered at similar price points - maybe because all our data comes from Google Analytics/Moz Proxies?
