Going by NPM, I'm seeing 225K downloads per week for react and 64K per week for Angular. Unfortunately, bower does not seem to collect download stats (I assume because downloads don't go through a Bower-controlled server), and I find it very likely that react usage is strongly correlated with NPM usage. React treats bower very much as a second-class citizen, even using a separate repo for its bower repository.
