Sony.
The N64 and Gamecube sucked, let's face it. Playstation was the way forward and if Playstation hadn't been made Nintendo wouldn't have learned from their mistakes and the Nintendo Wi-fi connection may not have been what it is today. Plus the Playstation gave birth to the:
Crash bandicoot series
Spyro Series
The '3D' Final Fantasy series
Ape escape
And it had classics like:
Soul blade
Suikoden II
Klonoa
Then the PS2 came and, scew Mario and Link, it spawned the greatest series of all time:
Kingdom Hearts.
I rest my case.
