Although I haven't heard much about the ps4, they both have their ups and downs. I personally think they Xbox one will suck, because they say that it'll burn the games to the Xbox and you will no longer be able to use the disc.
Ps4, xbox only changed there terible policies on trading games, and prices and such when the ps4 started outselling the xbox one by 3:1 an for that reason i will be staying with the ps4 just by how greedy windows is.
ps4 because its cheaper and most peoples tvs are in the family/living room and thats where most people spend most of there day and the xbox1 camera could be spying on you during that time unless your tv is in the basement or somewhere where you only play video games but i would still get the ps4
Microsoft is going to have a hard landing... REALLY hard. The console they're developing will not fly. From a personal, non-biased stand point (I'm a PC gamer, and I've owned both of the old consoles) I'll back the PS4.
