I almost have to compartmentalize it into 2 or 3 categories. SNES is probably my "overall" favorite, certainly in terms of its quality single and 2 player games. But N64 might be my favorite for multiplayer. Smash Bros, Mario Kart, Goldeneye, Mario Party, etc..
You also have Wii, which I love in terms of its ingenuity and how it pushed the boundaries of gaming. Playing Wii Tennis on launch day with my cousin felt like playing video games for the first time again. But it's still ultimately probably a close 2nd/3rd to SNES/N64, as its library was never amazing or as diverse as it could have been, especially on the third party front.
