I think Angular takes a considerable amount of time to wrap your head around. I think the largest issues that you will most likely run into is an ng-repeat with large collection of objects (which, due to dirty checking, may impact your site), memory leaking, and using multiple controllers or controller as syntax.

I used Mithril for a while and it opened up my eyes as far as thinking "functionally"; it makes your code easier to understand and extend.

If you use filters functionally with Angular, you can get great performance on large collections in a ng-repeat. Likewise, if you understand prototypical inheritance, it will make working with multiple controllers/states a lot easier.

I really enjoy developing Angular, but it took a lot of time to really process. jQuery just works out of the box, but for me, it feels like it is more for little snippets of codes across various pages. It just depends on what you are trying to do.
