I think, the biggest advantage of Principle is that you can make interactions within artboards. And also it is possible to make interactive UI elements which you can re-use anywhere. I think this is so much better way to build clean prototypes instead of making artboards for every single phase (like Invision Studio). At the end you have a messy design file with a lot of useless artboards. These tools I've tried can handle interactive design elements: Principle, Flinto, FramerX.
