BodyGuardz vs. Phantom Skinz ??

Now I'm doubting between 2 different options;

What do you guys think is the best choice, and is it good enough to replace the hard case cover?
I usually have my phone in my jeans pocket, so every now and than it MIGHT occure that something bumps into the phone.
(but only light of course, otherwise I would also damage my leg)
