Personal Computer.

PlayStation

Saturn. 2-D peaked here, then went the generic, lifeless 3-D route. A lot of great games defied genre back then, too.

Snes

SNES

Computer.

If it must be a console... SNES.

In my humble opinion: Consoles are good but nothing beats good old PC gaming a mouse and keyboard makes it so much easier than a controller on the consoles. Well who could go past: Warcraft 3 Diablo 2, World of Warcraft, Never Winter Nights 2, Dungeons and Dragons, PC versions of games are 9 times out of 10 better than console ports. Best online is on the PC and it is free.

PS and SNES but 5 years from now it may be something different.
