I think you need to understand what the issues are with previous frameworks and why React is different. React does save time. Maybe you've not built sufficiently complex apps in which state has bitten you in the ass, which isn't a bad thing. From experience, before React it was a nightmare as soon as the first dependency issues arose (whether that's data loading, UI flows or component hierarchies). React's fundamentals are in managing state via composition and functional-like declerative programming; it's hard to argue that any other frameworks take this clean, pure approach and really solved the problem. With Flux, Relay/GraphQL and ES7's decorators it's easier than ever to build pure, stateless components that are drop-in replacements for Angular's controller hell, or Marionette's awkward controllers.
