I was never a fanboy of any company, but after 2 Spigen cases for 2 different phones, from 2 different brands and many drops, I believe I won't even attempt to try another case company, not even experimentally. It's a guarantee that the phone won't suffer any damage. I even have a screen protector from the same company. Not even a scratch. I use the phone extremely hard, it should be for the trash by now and it's still like new.
Update after 2 years:
I still have the same phone with the same case and the same Spigen glass. In two years, the phone has probably fallen 50 times, with 40 of them being facedown. The only thing that happened? A small crack on the protective glass that you can't even see. I don't know if there's a better company to keep devices safe from everyday life. 5/5, the best company I've ever trusted.
