I had no issues creating a large SaaS application using Angular. If you keep up to date with plugins, and organize your folder structure, and create a good pattern you will have success with AngularJS. I recommend it to anybody who needs to develop a SPA. To those who ran into issues I feel bad for since they are used to flexibility of other frameworks. Having 12 developers in my team, AngularJS allowed us to keep us organized and communicate about constraints that framework puts. In many cases where we got frustrated we realized that framework was correct and we arranged the changes to our code that resulted in tremendous improvements. Keep using Angular it's good for your coding skills.
