It is best if you go for the machine that have the games that you wanna play. It is after all a gaming machinel. What is the point of buying a gaming console that doesn't have games that interest you.

For me personally, I'll go with PS4. It got the games that I want to play, and they have what I consider the best console life support. Sony have proven that they won't abandon old console when they release a new console for the past 3 generations now.
