Currently wrapping up my first commercial AngularJS project - I was outsourced by a client.

Prior to this contract I had no experience with it, now I've been using it nearly every day for the past month and a half, have run through the tutorials and implemented it on a side project of mine.

All that said, I will be stripping Angular out of my side project. It is something I am glad I learned for clients that demand it, but I wouldn't recommend it.

IMO Backbone with underscore templates are much cleaner and seem to perform much faster for my needs (no benchmarks performed on my end, but as a user my site certainly felt snappier prior to implementing Angular).
