Personally I prefer Xbox One. At this time, I feel it has the exclusives that I want to play. Forza Horizon 2 and Forza Motorsports 6 are best of class in their respective categories. Halo 5 is sure to be a massive hit. And it will also have titles like Gears of War 4 and timed exclusive Rise of the Tomb Raider coming up.

However, ps4 does have better hardware, which you can see when comparing multiplatform games. And of course, the Sony exclusives like Uncharted 4 are serious showcases of the ps4 capabilities. Even formerly multiplatform games like Street Fighter will be exclusive to ps4 (Street Fighter V), Guity Gear (Guilty Gear Xrd). The JRPGs (besides Final Fantasy) are also ps4 exclusive.

Lastly, the ps4 is just a lot more popular than Xbox One in Asia. So it will be easier to look for games, accessories, and players than Xbox One. So, unless you have some strong reason to choose Xbox One, the ps4 is easier to recommend. I also will buy a ps4 in the future, but mostly for the exclusives. For multiplatform I play on pc anyhow.
