IMO when already learning React it's no use learning Backbone at all. Better start with Flux. Backbone is not needed with React and although it is possible for them to be together (hell, we lived React+Backbone for almost a year), everything gets so much nicer when you can finally drop Backbone baggage. It might be possible though that in order to see where Flux shines, one has to sweat through limitations of Backbone. That may be valuable experience.
