I got into Vue because it was much easier to approach coming from a back-end (Python/Flask/Jinja or PHP/Symfony/Twig) perspective. It made it easy to adopt small pieces and learn as I went. React probably allows this sort of thing, too, but the documentation for Vue pointed it out first thing. Since I've started working with it, I haven't gotten a compelling reason to change to react or angular.

That's actually a pretty good difference I hadn't really thought about from the other perspective. React does a good job explaining the how and why, but is a bit more clinical leaving the last-mile as an exercise to the reader whereas Vue seems a bit more focused on coaching you.
I, personally, found Vue's documentation to be a bit less in-depth than I like and hadn't considered folks would prefer Vue's.
