I have yet to use Aurelia personally. However, I have used other frameworks that Rob Eisenberg has put out, including Durandal.js, and I had a good experience with it, despite that it never became as popular as AngularJS. If Aurelia works for you, I think that’s fantastic.
However, if it matters to you, I don’t think Aurelia has anywhere close to the ecosystem of React, Angular, and Vue and I don’t see it catching on. You don’t always have to go with what’s popular, of course, but there are many benefits to doing so. You get a lot of support from the community with React components, for example. People continue to push out neat innovations on top of React, like Next.js (server side rendered static app framework), React Music, Uber just pushed out a React Map GL component (http://uber.github.io/react-map-gl/#/) I mean, this is just the tip of the ice berg. You get massive benefits from being able to take advantage of tools like this.
