Why does everyone keep saying the reason why ps4 is better than Xbox one because its more powerful.

[Pezzilla]

I'm not sure if this is a reason, but the game install wait on the Xbox 1 are awful. I just started using my Xbox 1 a few hours ago and installing dead rising 3 took at least 35 minutes, installing games on the ps4 its no more than 3 minutes. BTW Hi! I'm New here.
