None, they're not worth it actually, take a better PC.
As for me, i would say to try the ps4 to get something different for once (and maybe better...or not), but it depend if you play on pc or not.
Xboxone is 100% useless (for me) if you have a good pc, while at least the ps4 will get some jap games.
Well, it's your choice, you can try handheld consoles too, or.... WIIU :cool:
