I'm the opposite. PS2 is like herpes...I've had a bunch of games that I've considered my possible "final PS2 game" but new ones are trickling out. Next up: Persona 4. I also keep finding old games to revisit or ones I've looked over.
I've played through a lot of games on it, though when I had an Xbox 1, I bought my multiplatform stuff on that instead.
edit: also, overall, NG+hurricane packs, NGBlack, Halo 2, DOA 3 and Ultimate, KOTOR, CvS2 online, and SF:Anniversary online were my favorite last gen games, so I think I got more enjoyment out of my Xbox than PS2. But PS2 is winning the long distance sprint (since these favorite games play on the 360/PC.)
