I'm glad you stepped away from React, which in my opinion is the most over-hyped JS platform in existence today (I have yet to see a website build on React with a for me acceptable user experience - I used to be a UI architect), and am curious to see how vue and storybook fare.
Well, Storybook is written in React. Netflix and Instagram are other applications which have been coded with React.
UX has nothing to do with the lib you are using. One can write apps with excellent UX with Vue.js and React.
I have seen platforms come and go, each with their pros and cons. I judge a platform by its ease of use for an average developer. A stellar developer can write something excellent no matter what tool they need to use. Unfortunately that doesn't apply to the majority of developers out there.
This too will pass.
