Above all, go with the system that has the most friends on it. You can own the best platform that the best specs in the world, but if you have 0 friends on it, you're going to have a lot less fun, guaranteed. If you have an equal spread of friends on either, just go with your preferred company. The PS4 and XB1 have similar specs, so it doesn't really matter in that regard, unless you think the number of pixels on the screen is a life-or-death matter.
