Angular is a complete framework. For large scale enterprise applications you can leverage it as it is more ‘batteries included’. React is more of a lib than a framework if you think about it and devs love it especially for state management using Redux. Vue sits in between and is lightweight only 33kb, you can use Vuex or Pina to manage state and its composition API is fantastic in V3. If ever you want to make an hybrid app without learning native languages or frameworks then pick Angular as the Ionic framework is written on top of it. The choice of the tool to use depends on what’s the task to be done really as all the three can get you there. I currently use Vue a lot at work but have good history writing Angular and Ionic.
