I think Vue.js has done a great job of avoiding a lot of the churn while staying competitive with other projects in terms of features and performance.
The core library of React seems well managed, but the accompanying ecosystem of 3rd-party tools for styling, routing, state management, etc seem to be constantly changing.
Meanwhile in Vue land, the critical packages have remained fairly stable and are all maintained by the core team. You get support for styling and transitions out of the box; for most other things (routing, state management, etc) there is one well-maintained library (as opposed to a bunch of options of varying quality that you need to sift through).
I've been using Vue.js for 10 years at this point, and have been using the composition API for the last 5. The older options API is still viable as well.
