Both have such a huge library of fantastic games. In my opinion, the best libraries overall of any generation of video games. I think they existed during an era of video game development where there the market had not fully digested what a commodity video games could be, so there was space for a lot of experimentation and discovery. Off the top of my head, the SNES has…
Donkey Kong Countries 1, 2, and 3
Final Fantasies 4, 5, and 6
Super Mario World
Yoshi’s Island
Super Metroid
F-Zero
Star Fox
Mega Man 7
Mega Man X, X2, and X3
Breath of Fire 1 and 2
Rock and Roll Racing
Earthbound
Secret of Mana (and sequels if in this hypothetical we’re not being region-locked)
Secret of Evermore
Terranigma
Skyblazer
Hook
Street Fighter 2 (and others)
Final Fight 1, 2, and 3
Killer Instinct
Super Mario RPG
Joe and Mac 1 and 2
Soul Blazer
Chrono Trigger
Zelda: A Link to the Past
Mario Kart
Shadowrun
Demon’s Crest
Super Ghouls and Ghosts
Castlevania Dracula X
Super Castlevania 4
Mortal Kombats 1, 2, and 3
Illusion of Gaia
Dragon Quests
Star Ocean
Lufia
Front Mission
7th Saga
Ogre Battle
Harvest Moon
Tales of Phantasia
… I’ll leave it there, but the list goes on, the SNES has a library that is burgeoning with bangers. The PSX is, too, but I feel hesitant to ruin the comments page with another list.
