No doubt the SNES from it's generation.

PSX from it's gen as well, though the N64 did have a few wonderful gems on it.

Pretty much Sony from then on as far as consoles go. PS2 just had to many golden RPG's, as well as PS3 being the best system for the genre of it's gen. As well as titles like Infamous.

PS4 is winning it this gen thus far, though I refuse to get an XBone, and PS4 has gotten a lot more use then my Wii U.
