On big project, it becomes impossible to optimize the DOM interaction yourself, so you start to do very inefficient operations for sanity's sake. React on the other hand abstract that for you.
I had a project with Angular where one page was really slow. I re-implemented it with backbone / jquery, it was a bit faster but really hard to read and maintain. With React, the code was simpler AND faster, which I was really surprised about.
