I have a commuter case and a reusable screen protector I got off line. I dropped my bionic once and put little chips into the screen.
Gorilla glass only seems to protect better than normal glass at the CES demos. I personally have never found it to be anything to write home about. There are a ton of RAZR owners who have dropped their phones from waist height or less and it cracked.
I may be wrong but I don't think gorilla glass helps much with drops as much a it does scratches.
