In another comment I mention that the biggest conceptual improvement that Marko offers is async and streaming rendering. Async changes how you think about passing data to your view (you start rendering immediately and you can retrieve backend data asynchronously to start rendering parts of the page asynchronously). Also, Marko is not tightly coupled to a VDOM (while React is) and because Marko is not tightly coupled to VDOM rendering we can achieve significantly better performance (sometimes over an oder magnitude faster than React on the server) and this absolutely can make a difference. The slowness of React (and the sync rendering) were huge blockers from the very beginning when we considered using React at eBay. --Marko author
