Difficult to ascertain. Sales wise of course Sony will sell more. It was N64's 388 worldwide games vs Sony's 4,074 titles. More games than you could possibly try + Lower prices + higher install base will lead to more game sales and frankly I have seen so many more "experimental" titles on Playstation.

Never thought i'd be playing as a beach ball escaping a maze while eating watermelons and listening to egyptian trance but it happened on Playstation.

Plus Sony always felt like a "global" console. They expanded the user base to not only non gamers but a truly international audience (latin america, middle east etc.) It was probably the modchips that made it happen but still.

But "winning the console war" is more than just raw sales. For example, of that extremely small 388 titles it is astounding how many of those games have won numerous prestigious awards, were genre defining, moved its genre in a direction that all others copied, or are still cited as one of the best games of all time.

The N64 really laid down an entire historial footprint for the millennial generation despite its significantly smaller sales. I guess a lot of that is down to Nintendo and many of their games demonstrating why they have been in a league of their own. But the console also had superb titles released by third parties as well.
