I just use the bumper from google on my nexus 4. So far I've dropped my phone at least 15 times at around the 3 foot level onto hard surfaces such as wood floors and cement and stone tiles. No breaks or problems in 2 years.
I also use screen protectors because I work with granite and fingers get dirty with fine grains of quartz, stone and diamond. It took 1 week before I scratched my old phone and I've not had the guts to see if the newer version of gorilla glass makes a difference, my guess is no considering my screen protectors are scratched to hell.
