PS4 have had superior Indie Game Support all the way, obviously. However, we should admit that the exclusives have been a bit more favorable to the XB1 side so far. What has stuck to my mind, good games or not...
XB1 : Forza, Dead Rising 3, Ryse of Rome, Titanfall, Killer Instinct, Plants vs Zombies GW
PS4 : Killzone SF, Knack, Injustice Among Gods, DC Universe, Outlast, Infamous SS
so it's a pretty balanced competition so far, but XB1 is slightly ahead because of FORZA. PS4 just doesn't yet have an answer for that. If Driveclub had been released already, it would be in perfect balance (excluding the indies).
However, MS used most of its ammo already while Sony is yet to show most... They were not concerned either since they were mostly supply constrained. They will now start releasing exclusives such as the Last of US remastered and Driveclub, and then the real show will begin for Sony...
