The first 3-4 years of the PS3 was pretty bad, you had exclusives like Lair which were generally bad games or you had exclusives like Heavenly Sword which never hit the mark. The first Uncharted game does not hold up well but that, it's sequel and Demon's Souls were the only bright spots as far as games that had first party involvement.
First of all, if we start talking about games that don't hold up well then even legendary consoles like NES can be dismissed; " NES never had many good games". I think 99% of the NES' library is unplayable these days either because they're too boring and/or unfairly difficult now, but it is a fact that it had an amazing, unrivaled library during it's own generation.
Anyway, that's not true, here's a nice list of well recieved games from the PS3's first 4 years:
God of War 3
Katamari Forever
Tekken 6
Infamous
Devil May Cry 4
Uncharted (multiple)
Ridge Racer 7
Heavy Rain
Little Big Planet
Ratchet & Clank (multiple)
Killzone 2
Heavenly Sword
Resonance of Fate
Valkyrie Chronicles
Resistance (multiple)
Warhawks
Yakuza 3
Siren
Demon's Souls
Metal Gear Solid 4
Mod Nation Racers
Lots more games that received mixed reception too (Genji, Socom, etc), can't even list them all. Plenty of smaller games (Bomberman Ultra, Lumines) which I'm not listing either. Of course, I've excluded multiplatform titles, of which there were many good ones unlike today, but that's more of a critique of the industry as a whole. Oh, and I ignored even well received sports games.
I don't even like PS3 that much, so I'm not biased for it. A lot of these games weren't for me, but it had new, original games in spades--just many were not to my taste. It's just an objective fact that you're wrong, PS4 had less to offer, and PS5 has virtually nothing.
If you'd care to list PS4's exclusives in a similar fashion, you'd find yourself coming up short.
