I like the idea of Lightworks. One of my heroes, Thelma Schoonmaker has been using it for the past thirty years. Her work is evidence enough of its promise. I've evaluated the software and, at the time I reviewed it (late 2014), I felt it a lot of nice things in one package, but not quite developed enough.
I don't really get a sense of where my data is being stored. It's not intuitive what is happening to it and that makes me wary. If you have an assistant editor who knows it well, it's a non-issue. If you're on your own, though, it may take you some time to get up to speed.
Give it a try before you commit to it. The small user base should be mentioned.
I do post-production for web, online media, commercials, fine art and music videos. I've yet to immerse myself enough in the software to see a unique benefit it offered opposed to other NLEs.
