My vote is for the PS1 because of it's great library of JRPG. Suikoden I and II, FF VII-IX, FF Tactics, Breath of Fire 3, Legend of Legaia, Chrono Cross, Alundra, Legend of the Dragoon, Xenogears, Grandia, Wild arms 1 & 2 and lot's lot's more.
It also has RE series, Silent hill, MGS, Tomb Raider, Twisted Metal, Crash Bandicoot series and many more.
SNES is also a great system many great games too FF IV and VI, Chrono Trigger, Lufia, DK, Mario of course and many more.
