Xbox 360 might be easier to hack but keeping the cheats safe is the problem, PS3 on the other hand if you have a safe cheat it wont get patched until months later.
i say its easyer to hack on a ps3 cuz its os is a chopped down version of lynix and xbox 3600 has its own os so ps3 is easyer to hack but for modding 360 is easyer to change the firmare ext
