Redux is only a little more work/complexity than the "singleton state class" approach but brings a lot more benefits: timetraveling debugger, serialization of the state (i.e. to localStorage to allow multi-tab operation or resume after tab was closed) and separation of pure HTML/Visual Components versus Container components. Oftentimes beginner would create just a single React component that references the state - which immediately couples the visual parts of your Application to your data, making it harder to introduce automated testing later on. When using the smart/dumb pattern together with react-redux it is very straightforward to come out with a good architecture, that does not mix ui and business logic/data handling.
