While I think the PS1 had a better overall library. Having played both recently I would say that the N64's graphics held up better. They were both great amazing consoles though. I kinda wish we still lived in a 2 console world actually. Where normal people could afford both. Oh well.
Back in the day I was a Saturn guy. Just played Area 51 on it this morning.
