id say PS4, the controller is strictly personal preference so it really boils down to what you feel comfortable with, i don't have any problems with either xbox or playstation controller layout again 'personal preference' but currently the PS4 is getting the majority of exclusive DLC ie Destiny (before the beta i wasn't sure but after playing it, it's a game i sure would like to get, for those saying it's not halo well that's obvious but as it's a Bungie game it will only get better regardless on what console it's on).
