What this update does do is fix some bugs and brings added stability to the model. Bug fixes and enhanced stability are the smartphone world's equivalent of saying that a blind date has a great personality. This update doesn't have the beauty of Android 4.2.2, but is a necessity to make the device run at its best. In fact, you might find your battery running a little bit longer after this update is installed.
You can see if the update has arrived OTA by going to Settings > About Phone > System Updates. Or, you can hook up your Samsung GALAXY Note II to your PC and see if you can pull the update out of Samsung Kies.
