What are the pros/cons of swapping Blaze with React?

React is faster.

React is more complexity.

We discussed about it a while ago

Reactjs, what are the benefits vs Blaze?

I’ve been trying out the recent React package for Meteor (react-meteor) and after going through the leaderboard example I started to wonder what the advantage of using react over blaze is. I realise there’s an already established library of components (which I’m yet to work out how to use with meteor), but other than that, what does react do that blaze doesn’t?
