The PS4 and the Xbox One are both a great console. They share almost the same features, they do what it's supposed to do, the graphics look amazing. The PS4 is more focused on gaming, while the Xbox One is more focused on the entertainment platform.
If you want to know which one is better, than you can read this:
PS4:
-Hard Drive can be upgraded by sliding off the top cover, opening up a few screws, and putting in the new hard drive
-More focused on gaming
-Controller feels a bit more better (personally. I've held both controllers, and I find the PS4 more fitting. For my hands atleast)
-Smaller and doesn't take up as much space
-Starts up faster
-Cannot use external hdd to install games on
-Has PS2 game emulation (Doesn't read PS2 game discs, you have to buy the games off the PS store for a cheap price)
-Doesn't read CDs
-Might become 4k with the rumored PS4K console
-Getting virtual reality
-Has 2 USB Ports (A usb hub can be purchased to get even more ports)
-Has rest mode (System is semi-turned off, lower power consumption, can charge controllers and other devices, can download firmware updates and game updates, no fan activity in rest mode, maybe a bit but VERY hard to tell)
-Power supply is internal, no power brick required
-Uses newer ram
Xbox One
-Can use External Hard Drives to install games on
-Hard Drive cannot be upgraded, you would have to buy a new xbox to get a bigger storage amount
-Supports backwards compatibility for some 360 games

-Only has 1 usb port on the left side of the console, and 2 on the back, makes it 3 but would be better at the front (hub can be purchased for more ports)

-More entertainment focused, a bit of gaming
-Requires AA batteries to use controller (Charge and play kit needs to be purchased to charge batteries and play)
