Once you understand how Angular works internally and not just in a tutorial sense, it can be very powerful. Most of Angular's quirks can be worked around using common sense, and as in some cases, using the right tools, understanding Angular isn't a silver bullet goes a long way too. The issues my team encountered won't be encountered by everyone, we were dealing with potentially thousands of items being in the page caused by infinite scrolling.

I get that some people think Angular is difficult, learning the basics is easy, learning how to use Angular the right way is the hard part. I think a lot of the issues people encounter using Angular are due to their own limited understanding of the framework. The documentation leaves a lot to be desired, but there are a lot of good blog posts out there like this which tell you upfront the issues and best practices.

The beautiful thing about Angular is that it is not difficult to get it to shows its warts, so you can work around or fix them. Combined with Batarang, you can get a pretty insightful look into your application and where you can improve it as well. A lot of the issues we've encountered were due to the fact someone on the team did something wrong expecting it to work, not Angular itself. Like a good woodworker, you've got to go with the grain, not against it.

I think if our application were being built from the ground up today, the team unanimously agrees that we would use something like React + Flux. But in our case, the business wouldn't be too happy with us throwing away old unit tested and battle-tested code in favour of something new and lean for the sake of a few milliseconds of browser performance.
