"One surprising take away is how much work and collective knowledge was required to bring out better performance from React, while Vue was fairly well optimised from the get-go."
Putting React in production mode, which affected your benchmark the most, isn't hard work.
My, not so surprising, take away from your benchmark is that the performance difference in your test is irrelevant. You did a lot more updates than the user needed to see and both Vue and React did splendid.
I'm still not fond of the vue.js templating over React's JSX. To me, JSX feels closer to HTML, and having the component rendering *in* the component instead of as a weird binding side effect just feels better to me.
It's relevant because code style, and project structure are as important as raw performance, especially given, that most applications don't need absolute responsiveness, or 500+ constantly updating fields/components from a feed.
Your comment was irrelevant because the article was talking about performance. It would be relevant if the article was a high level comparison between React and Vue covering both performance and code style, but it was not.
