My rankings would be

1. Wii U
2. Genesis
3. NES
4. Wii
5. 360

PC will always be number 1 due to its vast library, infinite backwards compatibility, freedom to tweak setting, best visuals and fps, etc.)

As far as non-pc...

1. SNES (Seriously: Super Metroid, FF4-6, Chrono Trigger, Zelda 3, Secret of Mana 1/2, DKC 1-3, Super Wario World 1-2, Tales of Phantasia, Castlevania 4, Demon's Crest, many many others...most importantly, most of these games have aged really well, unlike many N64 and ps1 games)

2. PS2 (wonderful games in all genres, some of the best rpgs and games ever that still play and look great)

3. NES (Not much needs to be said; so many classics on here)

4. PS1 (while most games have aged like poopoo, the system was super incredible for its time and has some wonderful, wonderful games)

5. Not sure. Probably the original Xbox. I think it is super underrated and I loved the library and controller. Then again, maybe wii for its uniqueness. But I think the entire 7th gen was absolutely terrible despite having some wonderful games

All I know is SNES and PS2 and far and away the best.

The Japanese version of the Xbox One  

1. Wii U
2. Nintendo 64
3. GameCube
4. PlayStation 2
5. SNES

Not in particular order:

- SNES (My first console)
- NES
- PS2 (My current console)
- PS1
- Wii

No offense but the N64 at number two and no PS2? Yuck, no thanks. Also, what's with this dismissive attitude toward Playstation consoles?

5. NES
4. 2600
3. Genesis
2. SNES
1. PS2

Edit: Also, what makes Nintendo so entitled to three (or more?!?) of the top five spots exactly?

5. NES (Famicom) / PS1
4. Wii
3. PS3
2. PS4
1. Wii U

all my home consoles in the top 5. :)

Why can I not vote between 360 and ps3? I much prefer 360 to ps3? Ps3 is just annoys me, great console though

7th gen, either PS3/360.

Not only for the modern games, but XBLA gave me many classics from my childhood that bridged generations (Doom 1/2, Duke Nukem, Gunstar heroes, Ultimate Mortal Kombat 3, Street Fighter 2 Turbo, Marvel vs Capcom 2, Sonic Adventure 2 Battle, Perfect Dark, Banjo Kazooie 1/2), etc. No console has ever given me so much classics alongside modern hits.

And those who say PS2, plenty of its greatest hits were ported over to PS3/360 as well. The 7th gen really had all gens rolled into one like no other before it.

Mostly based on my tastes but here we go.

1) SNES
2) PS2
3/4) PS1/NES (Couldn't rank one ahead of the other)
5) N64

I have nothing against the other systems, they're all great, I even own a 360. But these are what I've had the most fun playing :)
