Cheers for all your comments so far.
This offers an interesting insight for a non owner. As a soon to be owner of one of these consoles I rather listen to what an owner of both systems has to say, it's way more more useful than wading through the countless rubbish threads on the net and the arguments from fanboys.
I don't think this thread will help you either, I mean it looks like it's pretty even so far, some people use the xbox one more some use the PS4 more.
But, if you really are looking to buy a console then these are the things you should consider.
1. What games you like and which console has the exclusives that you play.
2. What console your friends have.
They are both good consoles, neither is better than the other. Just answer the questions above and you will be most of the way to making a choice, all the other stuff is just noise from fanboys.
Like, there is no point in buying the xbox one if the game you most want to play is "The Last of Us" And choosing the console based on how good the graphics are or how powerful is won't do you any good if all your friends have the other console playing an exclusive and you can't join them.
If answering the questions above isn't any help then you can consider the other things like power, Kinect etc.
