I'm gonna have to go with the Cube.

I want to say wii for Nintendo titles only... Its really hard to beat Galaxy, Brawl, Metroid Prime 3, Twilight Princess and many others... Yea there were a lot of terrible games too but I think Nintendo made some of its best games on the wii

Wii U

SNES, exactly 20 years ago, I got a SNES with Super Mario World, Super Mario Kart, Street Fighter 2 and Turtles in Time. It was my first home console.

Personally? GameCube
For the market? NES. Wii is second, but it's becoming apparent that its effects to expand the market haven't been as effective.

Until recently it was the Cube, but now i will say Wii U. The library of games is varied with some very original titles such as W101, Zombi U and Lego City, and Super Mario 3D world might just be a notch above the galaxy games. The future line up looks very rosy indeed. Gaming has also moved on, and now Wii U is my main entertainment hub i use it for nearly everything, inc internet browsing, movie streaming, drawing via art academy, social networking via Miiverse and i really love the gamepad. Online services are much improved and there is a huge amount of content on the ever improving E shop.

Snes

The N64 needs more loving.

I love 'em all, but for me it's the NES.

It single-handedly brought about a massive resurgence after the crash of '83, established the 3rd party business model, and made home gaming a permanent form of entertainment thanks to a host of ingenious software. Also holds the crown as the single most dominant home console of all time.

SNES takes it for me, but N64 comes extremely close. SNES had a more diverse library, but N64 has a lot of my all-time favorites games.
