I have been using angular.js a lot but I find the controller pattern to be too constraining. for example I cannot use promises outside the scope of a controller. I also find that while easy for simple example is get easily out of hands and I find myself having to revert to jQuery for lots of stuff. Consider for example the case of opening/closing a panel when a button is clicked. One can do this with angular but if you wish to add any animation to the panel, you have to use jQuery.
