While most of the Wii U's top games are on Switch, much the same goes for the PS3/PS4 to be honest.
Both have some gems that never made it over; Puppeteer, Resistance and Killzone on PS3, Xenoblade Chronicles X, Yoshi's Woolly World, and Splatoon on Wii U.
There are much more ps3 games that are on ps4 but also many more not on ps4 compare to wii u/switch simply because ps3 library was so much larger. Ff13, mgs4, tekken6, gta 4, red dead redemption, God of war and infamous series probably won't get ported to ps4 since its too late. Those are some of the games I want to play on ps4
The library in general is many times larger, so yeah, but a big chunk of PS3's major games made the jump like the Uncharted trilogy, TLOU, Mass Effect trilogy, Bioshock Trilogy, GTA5, God of War 3, the Assassin's Creed games, Tomb Raider, Heavy Rain, etc.
Nonetheless those games still count for PS3, just as games like BOTW, Mario Kart 8, Bayonetta 2, DKC Tropical Freeze, Mario 3D World, Pikmin 3, etc are still present and great on Wii U in spite of later ports to Switch.
