The PS2 wins this one. I tried to think of another console I enjoyed more, and I cannot. On Consoles I am first and foremost a JRPG player. My favorite JRPG's lives on the PS2 (Suikoden 3 and Wild Arms 3) and with Persona 3/FES/4, SMT DDS/Nocturne, Shadow Motherfucking Hearts, and Atelier Iris it could not be beaten.
These two were far more difficult. I loved Legend of the Dragoon, Chrono Cross (yes, I am one of the few who liked it more than Trigger), Suikoden 1/2 and FF 7-9, it just could not beat out the SNES. Chrono Trigger, FF 2-6, Secret of Mana, Secret of Evermore, Legend of Gaia and Earthbound.
#2 is the SNES
#3 is the PS1
Tho, as a gaming device the PC always wins.
