1: Wii
2: DS
3:GameCube.

Worst: None. All Nintendo Systems are amazing

Best)
1 - Dreamcast
2 - Super Nintendo
2 - Sega genesis

Worst)
The only good thing for PS2 was shadow of the colossus, but... PS2 is the worst!

best
1)Wii
2)N64
3)NDS


worst: a tie between the Cube and GBA.

For me they were all great being PC at the absolute top, but adding to the topic:

Best 3:
1. SNES
2. PS2
3. DS

Worst 3:
1. Atari Jaguar
2. Sega 32X
3. 3DO

Don't know why I bought these machines... but had to have them in my collection... yikes!

Although I don't really care about the hardware itself, the ones I played and enjoyed the most are:
1. PS2
2. N64
3. SNES

The worst would have to be the Wii. It's been disappointments over disappointments for me. I don't have my Donkey Kong and I don't have my Star Fox and they totally failed with Super Paper Mario. But I really do love Mario Kart Wii.
The future looks bright for the Wii though.

Best:

PC as it has the largest library and mods to boot. But assuming just consoles:

1. PS1: Advent of 3D and some of the best games and franchises were created this gen.
2. PS3: Sony's 1st party has really made some amazing games this gen.
3. SNES: Super Mario World, 'nuff said.

Worst: Probably 360. I refuse to pay to play online and most of the best games in its library I would prefer to play on PC. Not that it's bad, just the worst of a good bunch.

Best three in no particular order:

SNES
N64
Wii

My least favorite:

Gameboy Color

The best:
1. Snes
2. Gamecube
3. Wii


The worst:
I dunno

All time list

1. SNES
2. Xbox 360
3. PS2

Worst console ever "Apple Pippin"

PS2 wins lol.

xbox 360 is the worst.
