Better display on the Moto versus better camera on tthe G3, battery life should be about same. Take your pick. I would personally go with the Moto because I prefer the vivid AMOLED display and near-stock Android.
The ps3 is on official software and is able to play online, I haven't tried or even know how to jailbreak it so it's in it's original form.
The games that are being offered are bought online through the playstation store so I don't have the discs and no they are not pirated.
I can sell it for 22k excluding the shipping if it is required.
