For me it was a matter of dertemining which console would give me the most joy - the One won due to a number of things:

- I feel the controller is better to hold/use

- Better games, both lineup (titanfall!!!!!) and in the long run (such as Halo)

- The Kinect. Yes I said it! I think there is a lot of potential in the Kinect, and the fact that all Xboxs are shipped with one, means that developers will be more likely to add cool features to use it. If not, it can stay in the box.

I almost chose the PS4 due to the fact that that is what all my friends are playing on, and more gameplay in Assassins Creed, but that was not enough in the end.
