SNES:
Donkey Kong Country 3 is my fav DK game of all time
Terranigma is potentially my most fav JPG of all time
Runner's up-
I have a feeling a lot of GBA games I own possibly got released when the DS game out too, but I can't come up with any examples. I just get the feeling lol. Same with DS and PS1. I never had a NES back in the day but I bought one (since) a few years ago. If I had one back then I would possibly have mentioned that too.
PS2 games kept coming out too, so I imagine the winner of this thread will be either NES or PS2. But personally, some of my fav games of all time came out at the end (or after) the SNES's life cycle, so I'm gonna vote SNES.
I have (or have/had in the household): ZX Spectrum, Commodore 64, Amiga, NES, Sega Master System, Super Nintendo, Sega Megadrive, Gameboy, Playstation, Nintendo 64, Windows 95, Gameboy Colour, Windows 98, Sega Dreamcast, Gameboy Advance, PS2, Gamecube, Xbox, Windows XP, Nintendo DS, Xbox 360, Wii, PS3, Windows Vista, iPhone, Windows 7, 3DS, Wii U, PS4, Windows 10, PSVR, Switch, PS5 & PSVR2. :D
