This is not an Angular feature/issue, it is a consequence of how object equality works in Javascript. This article does a fairly good job in explaining what is going on in a pretty concise way and gives some examples. Check out the source of lodash's isEqual method (it will take you to the definition of baseIsEqualDeep eventually) to see how what you are trying to achieve can be done in pure JS.

In any case, I do not think there is an easy way to achieve this in Angular, you would have to re-write the way ng-options works and you probably do not want to go there...
