For our team React + Redux + Redux Saga + TypeScript has been a great way to develop our complex SPAs. We do use MobX selectively (dynamic forms), but the big benefits of the combination is the ability for our team to work productively without stomping on each other. Big factors are the explicit layout for domain models in the store, clear points for mutation, testable orchestrations via sagas, JSON schema validation and type generation.

The downside is the ceremony around it all but everything is so predictable and reliable it's a huge relief. Velocity is now good. We didn't choose this combination first off (via GraphQL, MobX, thunks), but the team decided that this combination was the best way for us to solve the issues we had encounter in the past.

I'm actually using a similar stack to you today -- redux + sagas, flow, json-schema.

However, in my experience, Vuex also has explicit stores and clear points for mutation -- Vuex stores are really clear and composable. It's also about 10 lines to get redux-sagas to working with Vuex.

If it weren't for react-native, I'd be pushing to use Vue + Vuex whenever possible. So I'm watching Weex with bated breath :) -- it's very cool that it's recently become an Apache Foundation project!
