I've been writing vue apps for internal use for about 1 year now at my company. I have not used Angular, but coming from Ember and React, It is by far the most productive framework I use. It is small and unopionated so I don't spend the massive amount of time I do fighting ember. I also don't have to constantly refactor it like the react code base (which has been through flux, redux, and now a new version of redux again, not to mention third party libraries only tracking the latest of alpha react projects) For simple apps, you write some immediately understandable code that gives you 80% of what you want, and the other 20% it gets out of the way and lets you do your thing. Only downside is the English-language community is very small compared to the other frameworks.
