Nothing beats native (vanilla) javascript when it comes to performance. Question boils down to "Do you want to spend time and resources in re-inventing the wheel by doing it yourself or just leveraging an external lib that does it for you?". Yes you sacrifice load time and performance but you save time and time is money. You can make your for loop faster by also caching the length of the array as such

for (var i = 0, len = $scope.filteredCartoList.length; i < len; i++)

This is going to work faster especially in IE because here you are caching the length of your $scope.filteredCartoList instead of calculating it every iteration of the loop.
