Well, if it's features you want, and not a gaming system just for, well, gaming then the Xbox One is your man. The X1 may not be the most powerful this current generation but it can do much more than the PS4 can. Since it's running a modified version of Windows 8 you can expect to find similar features such as "app snapping" which allows you to run two different apps at the same time or native Skype support. It also works really well as a multimedia system if you want to use it for movies or TV/Cable. Also, if you owned an Xbox360 during last gen you're in luck because it was announced that the Xbox One will have backwards compatibility with some games.
Though this is coming from someone who favors the PlayStation 4 as a gaming system (there's many good reasons, but I won't get into that right now since features is the main focus here :P)
