If you are in Stock firmware, Use the Internal memory update method. It is comfortable and safe; You can update like a Regular OTA Update. But if you were already using Rooted devices, You can try TWRP based Method. Don’t download any third-party apps; sometimes, it may trigger the updates process. There are a lot of new Gestures available in this Update, try them also. In my opinion, OnePlus 3/3T near Stock Android is better to compare with some other Custom Skin OS. So try to use this OS instead of a Custom OS. But the decision is your choice…:)
