The Switch has a very good library but a lot of it is built on games from previous platforms, like BOTW and Mario Kart 8 and Mario 3D World and NSMBU are Wii U games basically even Smash is basically an all-inclusive port of the Wii U game with new DLC, things like Witcher 3 and Skyrim are ports of older PS3/PS4 games.
The SNES has Super Mario World, Legend of Zelda: LttP, Super Metroid, Super Mario Kart, F-Zero, Final Fantasy V and VI, Chrono Trigger, Super Mario RPG, Street Fighter 2, Donkey Kong Country 1 and 2, Star Fox, Earthbound ... all of these games are certified classics.
I'm not sure how many of those the Switch has, which are actually just Switch-only games. Mario Odyssey, OK, Animal Crossing, sure, Splatoon 2 (though even this one takes a lot of its content from the Wii U game) perhaps, Luigi's Mansion 3, Pokemon Legends, but those SNES games mentioned above, they're still highly thought of like 25+ years later.
