Pros
Pro You can use common front-end stack
Use HTML, CSS and JS to build interfaces.
Pro Compiles to native platform code
A key difference is that Fuse uses JS exclusively for app logic while producing native code for everything else, including population and manipulation of the UI.
Pro Native performance
Pro OpenGL UI
With the option to use OpenGL based UI components, Fuse is the only of the three platforms that offer a reliable “write once, run everywhere” approach where designers can control responsive layout, look and feel down to points, pixels and percentages, keyframes and easing curves.
Cons
Con No clear path for starting a new project
Con Little reuse of web knowledge
Fuse doesn't support Angular or React so there is little reuse of existing web tech knowledge. The team have said they are exploring Angular 2 and then maybe React though.
