i have to display the JSON data in drop down list ,for that i have two options one of the options is By using ng-repeat and other one is ng-options.

ng-repeat code :

in html file :

<select>

<option ng-repeat=prod in testAccounts value={{prod.id}}>{{prod.name}}</option>

</select>

and in script file:

$http.get('document.json').success(function (data) 

{

    $scope.testAccounts = angular.fromJson(data);

 }

and other one ng-options :

in html file :

<select ng-model=selectedTestAccount ng-options=c as c.name for c in testAccounts1></select>

in script file:

$http.get('document.json').success(function (data) 

{

    $scope.testAccounts1 = data;

    $scope.selectedTestAccount = $scope.testAccounts1[0];

}

Now i want to know which one is best for my project to improve the performance .Any guidelines please .
