The trouble with the this thread is that the OP didn't really qualify the term 'best'. There is no way that Wii is the best gaming console over what they will do in the future. Look at it this way, if Nintendo had offered the SNES and the Wii at the same price back in the 1990s, which would you have bought? 20 years from now, the Wii with its new style of gaming will look ancient, along with anything else offered now.
Now, if best is what system that you feel you liked the most during its time, I'd go with the SNES. If best is sales, it is looking like the Wii will be best.
If best is what is best for the video game industry, best was NES, pretty much saving it, most would agree. But Wii could become the closest to that, if it brings in a ton of new casual gamers that then go on to play next generation consoles as well. Especially, the non-traditional ones of female and older gamers. And of course, to those new gamers, almost by definition, Wii is the best.
Torturing the numbers. Hear them scream.
