When to favor ng-if vs. ng-show/ng-hide?

Question

I understand that ng-show and ng-hide affect the class set on an element and that ng-if controls whether an element is rendered as par

From my experience:

1) If your page has a toggle that uses ng-if/ng-show to show/hide something, ng-if causes more of a browser delay (slower). For example: if you have a button used to toggle between two views, ng-show seems to be faster.

2) ng-if will create/destroy scope when it evaluates to true/false. If you have a controller attached to the ng-if, that controller code will get executed every time the ng-if evaluates to true. If you are using ng-show, the controller code only gets executed once. So if you have a button that toggles between multiple views, using ng-if and ng-show would make a huge difference in how you write your controller code.
