Which PS system has the best first party lineup, and why?

[Zippy6]

It's pretty close between PS3 and PS4. PS3 has the quantity of titles, but PS4 took the quality to the next level.

Uncharted 4, Horizon, Driveclub, Spiderman, God of War, Bloodborne, Ratchet, Ghost of Tsushima....

Nostalgia and variety makes me want to pick PS3 though.
