I vote for the Gamecube
No other system demonstrated Nintendo's first party strength like the little purple lunchbox
It may not have as many all time classics as the SNES or N64 but Nintendo was able to keep a console afloat for an entire generation almost by themselves and for that I give it the nod. Let's face it, if you had a Gamecube it's because you love Nintendo's first party line-up, end of story
Not to mention it brought some great new IPs like Pikmin and Animal Crossing
