Does the PS4 has the best library, is it why it's selling better?

Not really. The PS4 and Xone's libraries are pretty much even in my view--neither has a must-have game that isn't available on other platforms yet.

The real issue is that while there's lots of overlap in the games worth playing on both, the PS4 runs them better. And until 3 months ago, it was also $100 cheaper. That's what's doing more to drive sales I think.
