Ive got the xbox one, my brother has both consoles. IMO the ps4 is superior. The one is slow in comparison, and graphically at the moment nothing on the console comes close to killzone and what the ps4 is capable of. But if your mates have an xbox one then you've gotta go with that really.
Games list for both consoles should start improving soon. Forza is a let down tbh, but hopefully they should be bringing out another open world forza later this year.
