It seems that Vue has some points in its favor over React in terms of speed, despite React's finner control over reactivity. In the article they associate that with React's internals, but I wonder if also their philosophy to leverage the developer to trigger reactivity makes it easy to generate inefficient code, and in that case it may be that Vue's reactivity model has it's perks after all.
