Intellivision is best of course. Yes it has more power than the atari but power isn't important on a console this old, there's a plethora of more powerfull consoles but none have the sole of the intellivision. It's the original games, the unique 16 direction disk controller, the ovalay system and the innovative programers. It's the intellivision that gave us Utopia, Auto Racing and Sea Battle when other consoles only had Space Invaders, Pac Man and Breakout. All 6 games specified are greate games but the intellivision games took us to another dimension.
