I like the specs of the Z2. 1080p screen, 20,7 MP Camera, dust and waterproof, 3GB RAM, !front facing speakers!(that should be a standard)
The dbrand skin makes it unique. A skin should be enough to protect the phone from scratches.
Skins, like dbrands, are a good alternative to covers. They protect yout phone and maks it look cool, but without the bulkiness of a case.
Sony Xperia Z2 + dbrand skin + Linus Tech Tips = AWESOME
