Fewer games, more buggy releases.
While I don't know how the PC releases have been performance wise outside of TLOU because everyone knows that one but PS5 wise, while not as polished as PS4 releases, outside of a crash or two in Miles, Spider Man 2 and Ratchet, the only other issue I had was with Horizon Forbidden West where a button prompt didn't appear during a main story quest and I had to reload a previous save which cost me about two hours of game progress. But all in all, mostly minor issues that didn't affect my experience or with HFW, I was able to work around the issue.
Game wise, I was curious so I looked up the list for PS4 releases and this is for games that released as of the PS4 release or later through 2017. No PS/PS2/PS3/PSP/Vita ports and no DLC/expansions unless it's a standalone like First Light. All ratings in parenthesis are taken from Open Critic a few minutes ago.

19 games published by Sony for an overall rating of 83 (rounded up).
While the overall quantity is less than half of what Sony released during the PlayStation 4 generation in the same time period, the quality this generation is 9 points higher. Obviously, the next few years remains to be seen in regards to how many games Sony releases and their quality is but as someone who had PlayStation 4 as their primary gaming console last generation, im actually far more satisfied with Sony's output this generation than I was last generation.
For me personally, I completed Knack *, Infamous: First Light *, The Order: 1886, Until Dawn *, Alienation, Ratchet & Clank, Uncharted 4, Shadow of the Beast *, Horizon Zero Dawn, Matterfall, Nex Machina, Knack 2 *, Nioh * and Uncharted: The Lost Legacy for PS4.
For PS5, I have completed Miles Morales, Ratchet & Clank: Rift Apart, Horizon Forbidden West, God of War Ragnarok, Spider Man 2, Rise of the Ronin, Stellar Blade and Astro Bot. The PS4 games with an asterisk are games looking back I didn't need to play at all but with PS5, I have no regrets. Enjoyed every single game.
To each their own and all that but I personally would much rather have less games but they're better and I enjoy them more than more games that I end up playing just because I wanted somthing to play and then realize that I didn't need to play them. lol
