The PS2 is probably the best console ever from any company, imo, the DS is second, but I'll put handhelds aside for now.
The SNES is the best Nintendo console, gamewise.
The NES is second.
The N64 is third, only because it lacked any games from the RPG genre, besides Paper Mario, which is amazing.
The Gamecube and Wii are tied, because of Wind Waker pushing the cube up to current Wii levels.
Now, I do predict that the Wii will probably be the best Nintendo console before it's all said and done, simply because of sales, as sales determine developer support, and sales like the Wii has right now, mean the console is around for a long time, and already the Wii has reached Gamecube levels with actual games(Since ports do cancel out original games from previous consoles imo). By this time next year, when Kart, Okami, and Icarus have came out, it'll have passed the Cube by far.
Don't forget games like Bully are available for the Wii, which significantly diversify its library like the Gamecube did not. Killer 7 and No More Heroes cancel each other out.
In fact, I did a comparitive list Gamecube vs Wii not too long ago, and found that they were to close to call.
I don't need your console war.
It feeds the rich while it buries the poor.
You're power hungry, spinnin' stories, and bein' graphics whores.
I don't need your console war.
NO NO, NO NO NO.
