I just ordered one, but i have already tested one in many cons.
It's much better then xbox one, it have better performance for many games, and i can secure you that you will not have any problem with lan/internet games when you try to interact the multiplayer option, because long time ago the director of xbox twett about what would be the problem if you have to confirm all your games via internet? So, what about if you want to buy pirate games, you'll not able to play them because of the online verification, and when i was at the presentation of the xbox one you could observer the low performance that the console have while they where showing some games.
In my opinion ps4 all the way!
Just in case you need more info, i'll leave this chart. (I don't own the chart, i saw it in a post long time ago. So i saved it).
I got one, but I only really had time to set it up and play like 20 minutes of Need for Speed Rivals before I had to go to sleep cause I have to drive my roommate to work at 6am every day. I also got Knack and Lego Marvel.
