It's really easy to use as it has very intuitive UI which makes learning curve short! I've used this software during my internship at The Grommet where we're creating interactive content that are published across social media channels such like Instagram & Facebook etc with our own brand story called "The Storyteller".
This softwares have helped us produce more interesting visual assets within limited budget by using different tools from video editing all the way up until image processing/color correction so far i think there isn't anything bad about them because they do what you need most - producing good results quickly without compromising your work flow or production process too much :) As an indie developer who doesnot want spend thousands monthly just yet but also donnot wants compromise his workflow either while still being ableto save some money here nthere if needed then definitely go ahead since those things will come back when u make profit.
