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

[Bofferbrauer2]

PS2, followed by the PS1

Not only had they many exclusives, but those also stood out for being different to what the competition was offering. Starting with the PS3 the exclusives became increasingly similar both to each other and to what could be found on other platforms, they lost their uniqueness.

This is btw why I prefer Nintendo and Indie games nowadays: They still have this uniqueness which AAA, Sony and Microsoft imo have lost over the years.
