So both are 720p gameplay but ps3 is 1080p in cutscenes?
Seems like Square enix did a great job on the port if there is practically no difference between the versions. I would say just go with whichever controller you prefer. Maybe if you have a large tv that can do 1080p then go for the ps3 version.
The Ps3 version is definetly the better version but the gameplay is identical and graphics are identical. It's only resolution that is different. So if you've got a tv that can't do 1080p then the games are exactly the same. That's a good port.
