I only owned 3 so for me its second below n64 but way above wii

It will be on a respectable 2-3 place, with much lower overall quantity of the games, but very good avg quality.

I like it better than the Wii, and N64 and NES already.

Right now it's right behind the SNES and GCN.

Comparing it to the Wii: Better Donkey Kong Game, Better Mario Kart, A Pikmin which happens to be the best in the series. Unless something crazy happens, like Zelda U sucking or No Metroid being released, then it has beat the Wii. Also, Smash 4 will be better than Brawl, so there is that. Also Splatoon, and other new Ip's push it ahead in other ways.

Compared to the N64: Better 3D Mario, actual 2D Mario. Pikmin, etc. I feel like the N64 has aged really poorly as a console. Revolutionary for it's time, but now most of it's games are unplayable, or have received much much improved sequels.

The NES has just aged really poorly. I don't like much of anything on it because of the insane diffuclty, shoddy graphics, etc. Still has some great gems like the Mega Man games, and SMB3, but really not even close to the rest of Nintendo's consoles.

The Super Nintendo is still beating the Wii U at this point. It has one of the best Metroid games of all time, as well as one of the best Zelda and Mario games of all time. Lot's of great third party, etc. It will be hard for any console to beat the SNES. It's not personally my favorite, but looking at the system objectively, it will be pretty hard to beat.

The GCN is my favorite console of all time. It has my two favorite Metroid games ever, my favorite Zelda ever(WW), the best Smash Bros by far, the best Paper Mario game(which is also one of the greatest games of all time), two amazing Pikmin games, an absolutely godlike controller, cool third party like Timesplitters 2, SSX, Luigi's Mansion, Baten Kaitos, Rogue Squadron,Soul Caliber 2 with link, Wave Race, FZero GX, Eternal Darknessetc. It really is just a Godlike console for my gaming tastes. I think the Wii U has a better 3D Mario, Better Kart, Better Donkey Kong, and Better Pikmin, but it still has a ways to go before it beats the GCUBe. I think it can be done though.

For me the order goes Gamecube, N64, Wii, in terms of the consoles that I've owned. Including games (so my view of SNES and NES based on catalogue):

Gamecube
N64
SNES
Wii
NES

The Wii U is IMO up there with N64 and Gamecube, I have a great deal of love for both of those consoles and those top 2 positions jostle constantly. For me the Wii U is currently in joint 2nd, as it feels like a modern gamecube, although by the end of the gen I expect it to take the top position.

Well....

#1 - SNES
#2 - GC
#3 - Wii U
#4 - NES
#5 - N64
#6 - Wii

To early to say but doesn't look good. The N64 was short of games but beat the current wii U line-up day one with Mario 64 alone. Yet another mariokart and another smash doesn't wow me enough - even if they're the best yet.

It's built up a library of good games, and you should all buy a Wii U, but few games that I'll really remember and treasure.

Best. Nintendo games in HD for the very first time can't be beaten imo.

It´s the one i am playing most since Snes. 

In terms of quality i love it. In terms of games, i need more thirds, like destiny or the witcher. 

for me based on games I liked.

SNES
NES
N64
GCN
Wii
Wii U

I think number 2 behind NES. I have never had this much fun playing a console since the PSOne. Has everything you want in a console HD, Motion , a great online service that is free, and mini hand held (when the wife wants to watch her shows).
