PS3 has a far better third-party library in quantity and quality (most important). I don't know if I can say the PS3 has better first-party games. Even with the Wii U not having one of the stronger Nintendo first-party line-ups, it still rivals a lot of first-party lineups.
PS3 also is a multimedia juggernaut and has more robust online.
So, I will say PS3, even though I played the Wii U more overall and when it was a current platform. PS3 has almost always been about 15 years after the darn thing came out.
