PS4. But then again I have always been a biased Sony fan compared to a MS fan.
Either way, the PS44 has won a lot of people over compared to the Xbone after the shenanigans they pulled during their conferences and crap load of controversies they caused with their console, I know a lot of friends who are switching over too.
Plus the PS4 is cheaper than the Xbone in the UK anyway. Sony won't have the same domination like they had with the PS2, but the PS4 will lead the console war this generation.
