If you deciding to get XBO over PS4 because they raised price (reason unknown?), then you were choosing the PS4 for the wrong reasons to begin with.
Buy the 8th gen gaming console you would use, when you feel it has enough content for your tastes to justify that upgrade.
On just the value equation with PS+, there is no way I would choose any console other than any combination of owning PS3, PS4, PS-Vita
I also own the Wii U, because I love to play games with my family and it has the best 4 player family games of any console to date. There has never been a family-friendly party-game as good as Super Mario 3D World before.
The XBO currently offers me nothing I am interested in. If/when they do, I will consider making the purchase. I am looking at Quantum Break with that potential and not much else. I hate that they include Kinect that I don't want. I just don't believe in Kinect being a worthy inclusion just for voice-controls. It is an optional accessory with no optional game currently that even comes close to justifying its existence.
