Personally I'd stick with React and Redux for your view rendering and state management libraries. You're at a bump in the road right now regarding state management by the sounds of it, not your rendering library.
If you stick at learning and applying Redux in real applications you'll learn soooo much from the experience. Granted, the same could be said of any state management library, but given that most libraries these days solving a similar problem to Redux were inspired by Redux, I'd strongly advise investing the effort and time into learning that. You'll come out on the other side with a real appreciation of how to structure your app for growth and how to manage application state that you can apply to other libraries and implementations. You'll also have first-hand knowledge of the most popular front-end state management library currently around— something very potent to include in your toolbox of knowledge!
Perhaps you could share the part(s) of applying Redux that you're struggling with to help you overcome your current sticking points?
