A single grain of sand is harder than gorilla glass 3 and will much more easily scratch it than a relatively soft key, knife, etc.
No screen or screen protector is fully impervious to scratches. If you want something to protect the actual screen (for 'my precious!' purposes, or for eventual resale in mint condition), any SP will help towards that end. If you want to provide that protection without giving up the native feel and look, go with a tempered glass screen protector - which can be had in the same hardness rating as gorilla glass 3.
