For me this is a weird question...on paper? Sure, tough gen. Weird output pattern from Sony themselves, lots of cancelled/whiffed projects, big gaps in launches and in genres.
BUT
I have spent more unalloyed hours of enjoyment with my PS5 than almost all other consoles, including prior PS consoles. There are a lot of convergences that contribute to this: going from all the free starter games at the beginning of the gen--I would never have played Days Gone, God of War 2019 or Persona 5 otherwise--to the unprecedented variety available due to this weird remaster renaissance we're going though, including extremely latter-day localizations of niche games. I'm playing Final Fantasy 2 one minute, then Like A Dragon: Infinite Wealth the next, then MOON, then Baldur's Gate ONE, then Baldur's Gate 3 (note to self: play something other than an RPG, damn).
As someone who has always been interested in how games share DNA and influence another, this has been the console that has been the most fun to just freely time travel. Playing Saga Frontier 2 right after Final Fantasy 16 is a real holy shit moment...the legacy, however inadvertent, shines through. And there are still big, modern, popoff moments that have been great for me: I know Ragnarok is polarizing, but I found it to be the game I wish GoW 2019 had been in every way that mattered to me. Astrobot goes without saying.
The PS2 is a hard act for anyone to follow, but if it weren't for that system I might call PS5 my favorite PS console with a bullet.
