My attention has been split pretty evenly between Sony and Nintendo, so I don't know if this really counts.
PS1 was the clear Gen 5 winner. Only gen where 2nd place wasn't even remotely close. Ocarina of Time might be my favorite game of all time, but man, the N64 sucked the big one. Easily Nintendo's worst console.
I would also call the PS2 and PS3 better than the Gamecube and Wii, but not by so huge a margin as the PS1 and N64.
Every other gen, Nintendo has had the best console, and of course they've always had the best handheld.
