After ~1 yr of experience with Angular, I have to say I fully agree. Debugging is a pain, for a start, and so is delving into the source code. Plus, it's incredibly complex and opinionated and still it leaves it really easy to slip into really poor practices and untestable code (observe the complexity and verbosity of this best practice guide: https://github.com/mgechev/angularjs-style-guide). The real deal breaker is, however, performance in complex pages.
I much prefer to write my own controllers and models and use Reactjs for the views.
