Both systems are quite nice.

The PS4 has the Dualshock 4, which is, by far, the most comfortable controller I've ever used. They system is just slightly more powerful than the XBOne but is able to play games at a 1080p resolution natively. Honestly, that isn't a big concern. FPS is where it's at. It also installs the games to your HDD relatively quickly compared to the XBOne, which is wonderful. The difference is pretty great on that. Playstation Plus MORE than pays for itself with the access to games you get every month. So far, it's been a wonderful selection of indie games. Sony's whole acceptance on indies has been fantastic and only seems to be looking up from here. If you happen to have a Vita, then you can use that for Remote Play. It's a great feature.

As for the XBOne, I feel the interface is nicer and runs a bit smoother. The controller is the same great controller the XBox 360 had with the added caveat of rumble trigger buttons. I know it sounds strange, but it actually feels quite nice. You do have some nifty exclusives such as Peggle 2 and Titanfall. Supposedly, developer use and access to the cloud system Microsoft has created for the XBOne will help make up for any sort of deficiency in graphical power. Titanfall apparently uses this, but between the PC version and the XBOne, I can't really tell a difference other than the obvious fact that the PC version looks and runs better. The added bonuses of Skype calling and splitscreen is actually pretty cool as well. Much like PS+, you need XBox Live to do any sort of multiplayer for some games. Now... Unlike PS+, you need Live to access popular apps like Netflix and PS+ can be bypassed by Devs for certain types of games.

PS4 is the system to get right now.

... or, that's what I'd say if I didn't already have both. Honestly, I like them both quite a bit. I just wish there were more games to play on them. Though, the PS4 seems to be gaining more games quicker than the XBOne now too.

Gotta love winning a console.
