I'm not impressed with either of them really - What I want from a Games console is a single purpose item for playing games. I don't like the way everything is slowly joining together (eg microsoft account for xbox, phone, laptop, tablet etc) as it bugs me on a security level to have such a volume of info attached to one account or the move towards voice control etc as I think voice control is incredibly lazy!
Am happy they're releasing another edition of the 360 as it will enable us to keep picking them up second hand for a few more years if/when our current one gives up the ghost.
